So just because it wasn’t created by an army of programmers with 50 million venture capital it is not “professional”? I didn’t spend much time with it but from what I saw it was sharp and covered many corner cases (resizing, etc).

Because of it’s fundamental design decision of working on live pages instead of screenshots (which can be outdated easily) it is slow on sites like Techcruch that load WAY too many resources from WAY to many domains (just the DNS lookups probably make my browser dizzy). But I am betting they are targeting more professional sites than Techcrunch. Sites that actually care about giving their users a good experience instead of loading several hundred KB of shitty widgets.

Regarding loading speed - this blog’s design is bad for doing a post-page load JavaScript events. All the images have to download before the scipt will fire.

With so many images below the fold, this makes the demo sub-optimal here…net-net, I hope it’s a fluke, and one would get better perf elsewhere.

As for being slow — Techcrunch is an anomly that loads tons of scripts and addons. Take a look at the sample tour at http://www.demofuse.com to get a better idea of what speeds and features are possible with Demofuse.
