Thanks to everyone who attended my coupon class at the "Got to be NC" festival Friday afternoon at the state fairgrounds. And a big thanks to the folks at the North Carolina Department of Agriculture for inviting me to speak about some of my favorite topics: coupons and saving money on groceries.

The Wake County school system is getting recognition from BuzzFeed for its "sassy tweets."

This Monday BuzzFeed post looks at "16 Sassy Tweets From The Nation's 16th Largest School District." It shows how the district's Twitter account is showing a lot more attitude nowadays.

One example is Wake tweeting "How's that working so far?" to a student who says she won't go to bed until a weather delay is announced. When another student typed comfusing, Wake tweeted back "that 'M' in the word 'confusing' makes us want to keep you in class."

The Twitter account is maintained by the school system's communications staff, as Wake answered in one tweet. Wake's follow-up tweet was "Did you think it was the Easter bunny? Sorry 'bout that."

New York Times social media editor Daniel Victor argues that the oft used Twitter hashtag is mostly visual noise. Using #superbowl as an example, Victor points out your #superbowl hashtag was one of 3 million used in a five hour period. So it didn't likely get noticed. The more popular the hashtag, the less effective it becomes.

But what's the harm you may ask. Victor's response is pretty funny.

"Using a hashtag does no harm in the same way wood paneling does no harm to your station wagon, or a misspelled tattoo does no harm to your bicep."

Victor calls hashtags "aesthetically damaging" believing they are less likely to be retweeted.

But there are good uses for hashtags as Victor admits. They work well for smaller groups and subtext.

Regarding best practices for professionals, Victor makes some good points. As for the rest of Twitter users, I suspect most use hashtags more often than not to feel they are part of something larger.

Thanks to everyone who spent their Saturday morning with me learning about coupons, rebates and frugal living. And thanks for your amazing generosity to the Food Bank of Central and Eastern North Carolina. You donated 114 pounds of food and $37 in cash!

I really enjoyed meeting all of you and hope you will make the Centsible Saver blog a regular part of your day as you look for coupon deals, freebies and tips on saving money in your daily lives.

Look for new posts seven days a week. And be sure to check early Wednesday and Sunday mornings when I post the best sales and coupon match-ups at the supermarkets and drugstores -- all of them tailored to Triangle shoppers.

Hundreds of Raleigh residents and fans of the city have sent Twitter posts to actor Zach Galifianakis in the past day or so.

The tweets direct the former N.C. State University student and "Hangover" star to the Raleigh Economic Development website, where the city's boosters have a simple favor to ask: Make a sign with a "saying of your choice as to why you think Raleigh is the place to be" and pose with it in a photo.

Economic Development director James Sauls wants to bring some star power to the city's booth at the South by Southwest Conference next month in Austin. He'd like to have a life-size cutout of the actor holding the sign.

Former NFL players and Raleigh residents Terrence and Torry Holt are already on board with the project, offering Galifianakis a signed football if he participates.

Meanwhile, the Twitter trend continues to build under the hashtag #zachraleigh, with each post offering a unique plea to the actor.

The best one I've seen so far came from Raleigh City Councilman Russ Stephenson:

"Zack @Galifianakisz You served me @ Amedeos & I served you @ Sadlacks. Now lets serve #Raleigh"

Here's the link to the Raleigh Economic Development page explaining the request: http://www.raleigh4u.com/connect/zach-galifianakis.

N.C. State coach Mark Gottfried said he has talked to freshman forward T.J. Warren about the Twitter kerfuffle from earlier in the week and the two have moved on.

Former N.C. State player Thomas de Thaey was critical of Gottfried after Tuesday's 86-84 loss at Wake Forest.

"That's what happens when you're a great recruiter, but terrible coach!" de Thaey wrote on his Twitter account on Wednesday morning.

California and Illinois had laws take effect at the start of 2013 that prohibit employers from demanding passwords for social network accounts of workers and job applicants. The two states join Michigan which enacted a similar law in December. The Michigan law also bans educational institutions from dismissing or refusing to admit students who decline to provide account information.

The practice has become more common. Those needing jobs may feel as if they have little choice but to comply. I'm not sure I'd want to work with a company that would even request my passwords, but does North Carolina need similar law?

These laws do not protect workers from action over an inappropriate status update or tweet. So remember, you are what you tweet.

Superchunk drummer Jon Wurster has had plenty of posed-with-the-Gods moments over the past quarter-century, playing behind Bob Mould, John Darnielle, Ryan Adams and other indie-rock luminaries. But he's in the midst of a pretty incredible 15 minutes right now, after bearing witness to last Monday's flight-attendant freakout at New York City's LaGuardia Airport.

Wurster had a first-class seat on the ill-fated RDU-bound flight, which was repeatedly delayed before finally being canceled after a series of altercations between flight attendant Jose Serrano and passengers. Wurster spent the five-hour ordeal posting dispatches about the unfolding fiasco via Twitter ("The plane is here but the crew isn't. I Know I can fly this thing. I've seen all but one of the Hindenburg movies.") and Facebook ("What followed was a tidal wave of drama including: cops kicking off passengers, passengers leaving in protest, Jose crying, children crying, Jose quitting and the flight getting cancelled. I did get two bags of nuts, so that was good.").

Wurster was quoted in the New York Post (which identified him as "drummer at the indie rock band Superchunk") and has since been called on to recount the story on outlets including The Today Show, CNN and Going Off Track. No doubt this will be fodder for another comedy routine -- or perhaps the rock memoir I keep pestering him to write.

Meanwhile, back in Rockville, Superchunk's next local show is July 12 at Cat's Cradle.
