Trying out a new social networking site... TWITTER!

i've had a twitter account for awhile now but had never bothered using it. So, yup, this would be a good time to explore this social networking site that is all the craze these days. =]
Here's a screenshot of my twitter page!

After meddling with the website for quite awhile, I realised that it is not as easy to use as it seems. Or maybe I havent played around long enough. Sure, the basic idea is that you can microblog (140 words only), tag people in your post (the use of @), and "watch" your friends' tweets on your main log-in page. It all seems so interesting but as I was exploring the site, I kind of got frustrated.
Complain 1: I realised that it is not as easy to watch conversations between people. Sure, you know who's talking to who by seeing the
'@' sign, but to follow the conversation between them requires you to actually shuffle between the pages. It is not as straightforward as facebook's "wall-to-wall post" option where everything is neatly mapped out for you.
Complain 2: Even after seeing the FAQ page, i still have no idea what the '#' sign stands for! I had to google it, and in googling, found that there are more stuffs that I didnt know about twitter! :S Here's the website to see:

All in all, twitter is more than I expected (i.e. merely posting). Sure, easy to pick up but to discover the 'hidden' stuffs would require more probing. I can see how it can be interesting, though. (See my previous video showing Ellen using twitter for prize-giveaways!)
