Today I have come across a very nice site called microcommunity.org. It is a site for accumulating video collections. What I found very attractive about microcommunity.org is the absence of advertisements and the super neat layout. You can choose if you want your community closed and password controlled, or if you want visitors to be able to suggest/embed videos.
I have today started a mirocommunity which I hope will prove useful for me and my colleagues at work. My hope is that we shall share this site and build it up to be a great video collection to aid us in our work
