There's definitely room for competition. Most recently we've got Wix and Squarespace, but again they target the end user rather than developers. I think most people are willing to shell out a bit more for a local developer rather than an impersonal SaaS site.

At the moment I'm working on a prototype using Python and Flask, which seems like Django without all the cruft. Pretty much the only other options would be Ruby, Go, and Javascript. But I really like Python. :)
