I have been tweeting for quite sometime now but it is only in the last 2-3 months that I have really enjoyed it. There are 2 reasons for that and I urge you to try it yourself.

Twitter + TV
Have you ever tried tweeting while watching TV? It is so much fun! I started to do it while watching the F1 races and there is as much action on Twitter as there is on the circuit. And if the race gets boring — as it did for the Abu Dhabi one — watching the tweets were more entertaining! Even if you do not have Twitter account (d’oh, where have you been?), you can still check out what Twitterers are saying by checking out “what people are saying about” feature. Just type in what you wish to know (say ‘World AIDS Day’) then click on the search button to see the tweets about it. Of course, it is much more enjoying if you participate in the conversation so go get yourself a Twitter acount.
After you do that, you’ll find the relevant tweets faster by using the hashtag.
Comedy on Twitter
I love to laugh, which is why I love comedians. I love them even more when I discovered that a lot of my favourites are Twitterers, too (like Dara O’Briain)! I began to follow these people and now, I get a dose of their respective comedies by simply reading their tweets. It can be even hilarious when they converse and have a banter with each other! It’s stand-up comedy on Twitter! Here is my list of funny people — http://twitter.com/#/list/charlie74/coolnfunny

Ah, thanks for reminding me about Dara O’Briain! I saw him on TV here in Holland last year, and never found out who it was. He’s the funniest comedian I’ve ever seen!
Dara is really funny and he’s a genius, too! He studied Cosmology, methinks.
