I've added an easier way to embed tweets. There's no button yet but it's similar to the way you embed youtube and vimeo videos!

Say you want to embed this tweet: https://twitter.com/SpikeLee/status/307093047190093824

All you have to do is copy the tweet id, which consists in the underlined numbers at the end of the url and paste them between [tweet ]307093047190093824[/ tweet] tages (no spaces)

The result should look like this:

Thanks tiger0330 for the suggestion!
