That's why a site like biztoc.com makes sense — curation + aggregation.
It was written in big letters, "dont worry we wont spam".
3 minutes later: 2 emails in my inbox. One of them "BizToc is made possible by Mark Cuban & Thomas Marban. If you’re enjoying it, please invite your friends & colleagues."
This is pure spam and I do not like it.
And yes, I chose to hate them.
