In March, Twitter announced they had 140 million users, who send a total of 340 million tweets a day.  If you're one of the people who's obsessed with it, here are five annoying Twitter habits that you should break.

#1.)  Constantly Asking Things You Could Easily Look Up.  If you're on an eight-hour layover and want a recommendation for a good restaurant, that's fine. 

Just don't do it every time you go out for dinner.  As a general rule, if you can Google something, try that first.

#2.)  Tweeting Too Many Photos of Food.  Everyone has a camera on their phone now, but it's still surprising how many people post pictures of their lunch. 

Again, every now and then is okay.  But if you're doing it more than once a week, you're annoying people.

#3.)  Ignoring Your Followers.  Obviously not every message deserves a reply.  But when someone tweets you and says they like one of your posts, it's kind of rude if you don't respond.

CELEBRITIES can't respond to every single message on Twitter.  But if you only have a hundred followers, you probably have time.

#4.) Tweeting Links to Websites, and Not Including Any Context.  You should at least include a few words so people know what to expect when they click on it.  Especially if it's not safe for work.

Twitter automatically shortens a URL when you post it.  So even if you post a long link, you still have about 120 characters left.

#5.)  Adding Unnecessary Hashtags.  Hashtags are supposed to help you connect with people who have similar interests.

For example, if you write a hashtag . . . which is really just a pound sign . . . followed by the phrase "presidential debates," people who search for "presidential debates" on Twitter should find what you wrote.

But a lot of people use hashtags that are so unique, no one will ever search for them.

For example, last week Mario Lopez tweeted, "It's easy to quit.  It takes faith to go through."  Then he added "[hashtag]-Start-The-Week-Right."  And no one will ever search for "Start the Week Right" on Twitter.

That doesn't mean you shouldn't use crazy hashtags when you want to be goofy.  But don't do it too much or it gets annoying.  Plus, you look like you don't know what you're doing.  (BuzzFeed)
