I have been looking far and wide looking for the ultimate home page. This one has many very well done features, looks and ideas. It is clear that some time and work was put into this one.
However, it does have a ton of bugs, the flow and UI are close- but there are some snags, many websites are wildly misscategorized( Like Cars.com being in the "Going Green" category.)
When it comes to website inclusion it is a big danger to include every site in a category. I should disclose that I am working on a similar project and I spend hours a day on that segment alone. Lets say I am blitzing sports sites and looking for football. I might find 10 sites- but maybe 3 are great. Blindly listing them all is a big big mistake.
Also, the #&%^* toolbar buttons refuse to customize and they actually sent a few of the buggier icons( it always is the same few) all over the place. That rookie mistake was one star drop alone.
In short- this has blockbuster potential but it feels very beta. Keep developing it, put in the time and it could go from potential to greatness!
