re:Can I say that?

Yes, you can say that, as well as anything that helps to find ways to improve and is generally toned as a sane discussion and not just rant. SO, you're cool :)

You're right about "opinions" - they do, in a sense, clash with the idea of not posting about other members, but they are a dedicated place for that, so there we can use certain rules - like in Market, where one can post only if they bought a products, etc. In Profile's "opinions" we will be looking see more for limitations too, possibly just something like a "one can post only 1 opinion per week" or something like that and will moderate them.

One of the most important updates that we're preparing is that we'll be catching all new posts, comments, opinions, etc and would be able to moderate them without going to every corner of the site. So, hopefully, in a few weeks we'll turn Unity into a much cleaner and brighter place.
