Flow sounds really cool, a multi threaded browser engine. Most modern ones are forked from KHTML, an engine designed in the 90's before multi threading was possible for consumer computers.

They only have 8 developers on the team. I wish them well, but what do they have to offer that vendors and consumers really need? Do people really complain about Chromium being too slow? I wouldn't imagine, if most of the users on the web are using it. Then again I don't know about the niche mysterious world of elite internet browsing.
