I'm constantly impressed by some of the pithy, droll and sarcastic bios people write for their Twitter profiles. I thought it was worth sharing a few of my favourites:

@derekandkong: Born at a very young age I realised almost immediately that I knew very little.

@keithpitt: web developer (Ruby on Rails), geek, gamer and robot from the year 2143

@TheBloggess: I have friends in spite of myself.

@Cathie_Tranent: I am a wife I am a mother I work I blog I photograph I design tshirts I'm tired

@Wang_Wang (panda) : Black and white bear. Omnivore. Likes travel, eating bamboo and origami. I'm endangered, but I party like a rock star.

@bludgingwriter: Trying to finish writing a book while the TV brings up the three kids

@teedubya: ... SEO Jedi. Uber bullshittapotomous. Social Shaman. Pompous Windbag. I'm kind of a Medium Deal.

Unfortunately, we don't always notice these bios, as we visit Twitter.com less, instead using tweet tools such as Hootsuite. These tend to disconnect you from the bios, background images and other individual touches that people use to represent themselves. It's worth checking in to Twitter.com now and then to take a good look at your tweet pals.

What's with the pressure to be funny on Twitter?

I thought it was just me. And then I Googled it just in case (as you do). And I found I'm not the only one .. it's a big topic out there.

Apparently those 140 characters aren't simply about being clear and succinct. They need to be funny, pithy, whimsical ... or at the very least, sarcastic. If you don't get a few LOLs, LMFAO or Hee Hees a day, you're #failing.

This applies to tweets from journalists, social media commentators, web developers, retailers, the ordinary Joe in the street.

I once saw this tweet posted: "I'm not following X Company any more. They're just not funny". What the?

Sure, there's plenty of other themes on Twitter. Many of them far from funny.

There's the soapbox brigade lobbying for something or railing against something. There's earnest awareness raising, fundraising and cause-promoting tweets. But hotdamn, those funny Twitterers are the best aren't they? Even better: the fake accounts that tweet in character.

Sure, fake Twitter accounts are 'naughty' but hell they're creative. (But can be so disappointing when they stop tweeting. I enjoyed JackFknBauer while it lasted. And BrosLife just doesn't tweet enough!)
