The tags are plainly visible everywhere you go, such as under the “What are you doing entry box. This makes tagging your tweets quick and painless. This is something I’ve always thought we should have. It makes using hashtags even easier to use by just clicking them (see Tag Your Tweets).
The other thing I like is the handy top 10 Twitter trends feature that gives a quick look at the latest buzz on Twitter much like we see on Twitter search without having to go there.
