Is anyone from HN a member of some of mentioned networks? Is it of any value to you so far?
Should HN be on the list? Probably not if you define things narrowly as "social networks". But then this is certainly one of the top 10 entrepreneurial communities online.
if HN was on the article, think how many more articles on Erlang would come up? I think Mashable might be more frequented than Codinghorror.
I'm searching a really good community of IT entrepreneurs. Much like HN but with less programming and more business minded people. Didn't find it in this list.
I looked at the forum in cofoundr and the first post is titled "Just wanted to say hi".
From that list only TheFunded seems the most focused on the 'real' entrepreneurs. I wonder how much value does it actually hold.
