As is pleasingly typical of when I have an issue with Microsoft, I got a response to my complaints about GotDotNet. And it was a very good one. Thanks Andy! I'm sure people will be pleased to hear you're aware of the issues and are working on the problems.
Of course, I'm still not coming back just yet. :) The fact that the site should getting faster soon is great news, but like I said before, tools and stability are the main issue. I'd happily pitch in and write some decent tools myself, but I have lots of other projects that I need to work on first.
