Recently, I wanted include a Twitter feed in a website. My immediate thought was "I bet there's a jQuery plug-in that does that". And of course, there was one. In fact, there were quite a lot of them.
I tried a few, many of which had lots of impressive sounding features ("show all the tweets from user xyz that use the hashtag #foo and mention the word 'bar'!") . But I wasn't really happy with any of them, as they all felt a bit slow and bloated (probably due to the big list of features that I didn't actually need).
Done, without a jQuery plug-in in sight.
