The bookmarklet makes me sad because it could be so good, but still comes up short.
I was using it for a few weeks to translate Twitter since there are a few foreign language accounts I'm on. One problem it has all the time is that it usually gets the source language wrong the first time (goes English to Spanish when it should go Japanese to English). If there was a way to fix this it would be great. The JS to EN default is in the code, but it still would fail a lot until I do several tries.
The ACTUAL best was when Bing Translator was integrated INTO the Twitter aggregation webpage so I could translate only individual tweets. That was THE best. But the bookmarklet is an ok subsitute sort of.
And today it stopped working completely on Twitter.. ! What's happening out there... hello??
I tested it on another site and it still works, so... what's up?
Good luck, people!
