Seems to me it will have some good uses. The promo of it being "more human" is a stretch, yes, esp. given the actual programming language didn't look any friendlier than any other language imo (e.g. world<-[#div style: [user-select: "none" -webkit-user-select: "none" -moz-user-select: "none" children ...)
But it's nice of them to make a valiant effort at trying to create a new method of doing things. Reading the "What Eve Is" page is helpful:
Heh, as another commenter said below, "i see the first problem is that you're generating HTML". The nice thing is, that is in no way intrinsic to Eve. The @browser DB is a regular DB like any other that we happen to sync to the client, and the client has a bit of code (which users will be able to extend in the future with other functionality) that takes HTML-shaped records and turns them into actual DOM on the screen.
Since we are targeting programmers first right now, it seemed better to focus on other aspects of the editing experience than to try and re-invent document markup to start with. That said, we're not opposed to exploring that possibility down the road. If you have any thoughts on the subject I'd love to strike up a conversation on the mailing list [1].
http://programming.witheve.com/deepdives/whateveis.html "Being explicitly designed for data transformation, there are somethings that Eve will particularly excel at..." (after beta stage, of course)
That said, it'll be interesting to see what software people decide to create with it and where this system excels.
