For what Twitter is today, I'm sure they are. They are essentially the world's largest chat room except every participant gets to curate their own experience (plus it's all indexed). Maybe their revenue stream won't be directly a tech product but will certainly be the result of one.

What do you mean by "won't be directly"? It seems like you're implying they're not making money today, which they most certainly are. They do have a revenue stream. Several, really, between promoted tweets, promoted accounts, and the firehose.
