Twitter? Not my cup of tea, thank you

I'm truly amazed by the popularity of a site like Twitter. I joined about two years ago and up until today I still couldn't figure out why it's so popular. First of all, I find it a very cold an impersonal medium to communicate. It  seems to me most tweeters are using Twitter for advertising. Secondly, it looks like everyone on there speaks solo. Try as hard as I can I just never can catch up where certain remarks came from or to who it's directed. Thirdly, and the thing that annoys me most, it feels as if tweeters are speaking a strange language of their own. Most of the time I don't understand a word of it, perhaps because most of the time there is no word, just letters and digits etc. Here's some examples of what I mean:
