To tweet, or not to tweet? That is the question not enough people are asking.

According to a recent study from the Pew Research Center, daily adult usage has doubled from May 2011 to May 2012, with 31 percent of 18 to 24-year-olds signed up. The expansion of accounts throughout the last year has many novice users coming to terms with what is considered socially acceptable Twitter behavior. Even experienced tweeters are now confronted with a much more complex system than in 2006, with automated posts, promotional tweets, and constantly morphing features.

While Twitter's slogan, "join the conversation," encourages users to engage thoughtfully with followers and friends, that's not always the case. Indeed, we've seen (and unfollowed) our fair share of careless tweeters; we also noticed a few trends among these users (over-Instagramming, hashtagging everything, tweeting under the influence).

Check out the slideshow (below) to see the 15 things you should definitely stop tweeting. Then, tell us what your biggest pet peeve is on Twitter. Share your opinions with us in the comments, or tweet it to @HuffPostTech. We might respond…if you follow the rules.

Feeling nostalgic? Check out our gallery of 19 tweets from 2006 that you'd never see in 2012 (here).

  • Pictures Of Your Debit Cards

    Stop with these photos! Seeing your account number and name is too much information to willingly give away. To curb this recent trend, <a href="https://twitter.com/NeedADebitCard" target="_hplink">@NeedADebitCard </a>has started calling people out on Twitter who pose with their plastic.

  • Too Many Hashtags

    #One or #two #hashtags is #enough, #people. Also is #FF an outdated fad yet? #Itshouldbe #Imsoironic. Oh and #PS Don't you love #ridiculouslylonghashtags?

  • Requests For Retweets

    There is a certain desperateness if all of your tweets scream "Plz RT!" or "RT if you love this!" We probably won't do as we're told.

  • Your Own Twitter Handle

    That's like talking about yourself in third person. (And you probably shouldn't do that either.)

  • Humblebrags

    Ah, the humblebrag: "People keep telling me I look great today, but I'm so fat!" "This picture of me is horrible, but thanks for all the compliments!" The only boasts we like are those aggregated by <a href="https://twitter.com/Humblebrag/" target="_hplink">@humblebrag</a> -- and that's because all of your subtle swagger is being mocked.

  • Drunken Tweets

    We know you go out with your friends on Friday night. And that's totally fine -- but maybe when you puke in the back of a taxi at 4am, you should keep those tweets to yourself? Or maybe not... We kind of like reminding you to delete them the next day.

  • Your Klout Score

    So you're influential about the topic of "coffee?" Wow. Your klout might <em>actually</em> be worth a #humblebrag.

  • Rapid-Fire Instagram Pics All Day

    We love Instagram. But, alas, there can be too much of a good thing. It's bothersome when you tweet 17 pictures of your dog or your baby a day. And might that also <a href="http://www.huffingtonpost.com/2012/06/26/instagram-tips_n_1557614.html" target="_hplink">annoy your Instagram followers?</a> For a fun little Insta-mocking Twitter account, check out <a href="https://twitter.com/textigram" target="_hplink">@textigram</a>, which tweets what your photos would be if they were described via text. "Latte with heart shape in foam" and "Wing of airplane, hashtagged ‪#flying‬" are some recognizable examples.

  • 'Good Morning' Tweets

    Imagine if we all tweeted "good morning" or "good night" with no updates, anecdotes, or witticisms. The Twittersphere would be a pretty boring place. Don't put us back to sleep in the a.m.; resist the early morning greeting to no one in particular.

  • Food Pics At Every Meal

    Especially if they are photos of the fast food variety. We can only see but so many Dorito tacos and Jr. Bacon Cheeseburgers.

  • Every Place You Check Into On Foursquare

    We don't want to see an automated message about your trip to Dunkin' Donuts every morning.

  • Tweets About You Working Hard

    It makes us feel lazy, especially on a Tuesday night when we're out at dinner.

  • Passive Agressive Tweets

    These tweets are awkward, angsty, and remind us of MySpace circa 2004. Just take a punch, why don't ya?

  • Celebrity Retweets

    There's a reason why some of us don't follow Kim Kardashian or Katy Perry on Twitter. Kindly keep the latest gossip on your own newsfeed.

  • Tweets About How Many Followers You Have

    You win some; you lose some. Either way, we don't really care about your follower count just like you probably don't care about ours.
