Well to be honest i will say this:
this is the first version of the C9 web site in a while that seems to be ok in terms of beeing up and working most of the time so that we are not all having to complain about that.
BUT I do feel that WAY WAY more could be done to make this a really top rate site. however at this point i am not looking for them to do much more to it. why? that's a long list of things that i will just say it follows my general concern for what MSFT is doing as a whole.
one thing i would love to see fixed is the problem with formatting / css that happens to threads sometimes... can make them un-readable. if that's a side effect of allowing custom css then get rid of that option, we do not need it.
