Last weekend I spent about 5 hours testing out Heroku and MongoDB and I created designblo.gs. The idea behind it was to create a resource that I could point the people who asked me who else to follow for advice. Not only that, but as I plan to include popular blogs and even non-popular ones, even the Vet's can find blogs they've not heard of before.
I have a few more people I would like to ask. Any suggestions on features or people welcome.
So check out designblo.gs now.
As for MongoDB. I still am of the same belief that I was before. It works somewhat fast for development but it's not really for production. The ORMs are also still too immature.
