Super! To finish it off a little bit, you could add "content management" to it (as a "slogan" or extension to "webbler" like; "webbler content management").
About #13, we like the idea of the playfullness, if you could make it a little less "sony ericsson" (if it's possible anyway), and more into the building block / module idea, it would make a great logo i think!
Thanks!
