So, Twitter is allegedly abandoning Ruby on Rails. I must say I'm surprised at this; while it (RoR) is clearly no speed demon, is it really bad enough that they have to run from it like that? Somehow, I can't imagine that RoR alone is the problem; I suspect that there may be some underlying brokenness which they are, for whatever reason, unable or unwilling to deal with.

Apparently, they're looking at PHP or Java. Oh, god, more PHP. Why won't it just die? Hate, hate, hate.

No Erlang mentioned, even though it is theoretically more or less ideal for this sort of application. I hear that they looked at it before, but it was too difficult for them, or something; this is mentioned in the now-famous Scaling Twitter presentation.


Ah, remember when Ruby on Rails was the future, and could do no wrong?
