Hi Mike
I see what you're saying about the need for blog separattion between you guys and us end users and think I agree as sometimes, visiting a blog/site and scanning through it can be quite easy to mis-read posts from users and the site owner/s etc.
As for users blogging about EntitySpaces, naturally I can only speak for myself, but part of the reason I use ES is because it (on the whole) just slots right in there and I don't have to devote oodles of time to it so perhaps it is too narrow a field to blog about from my perspective - others opinions may vary though.
I think, again, if it were me, that until a decision had been made then I would be tempted to just remove the blog from this (community) section of the web site as people may mistakingly think it is the one used by your team and as it doesn't mirror the dasBlog entries people may miss out on them.
Anyway, just my 2p - I'm sure others will chip in at some point
Cheers
Martin
