As Danny Sullivan points out, Cuban is an investor in Mahalo, which is an aggregator extraordinaire.
And in 2008 at the TechCrunch50 conference, Cuban said he’d like to be an investor in news aggregator TechMeme. He says: “Gabe from TechMeme, I’ve been running after him for two years to try to let me do something with him because I think its a brilliant idea and I think I can add value…I try to stick to things that are strategic to me that I think are fun that I think are game changing.”
Cuban was mostly railing on Google News in his talk, but TechMeme has a similar model of linking to stories with a short excerpt. You can watch the entire interview here.
I’ve emailed Mark to get see if he wants to talk more about this, because I continue to be more than confused.
