You could, Xanga as well, but it was still less connected. People complain about recommendation systems on YouTube and Facebook and Reddit, but one thing that they do well is give people more reach that they probably wouldn't have gotten before.

I've found so many interesting YouTube videos from people that I haven't ever heard of, just because of YouTube recommending them to me. Stuff like that didn't really exist for quite awhile; for a long time the best you had was aggregator sites like ThatGuyWithTheGlasses.com or similar sites.
