I've been into the "personal website" world as well recently, and one thing I've noticed is a lot of personal websites end up linking to each other, or have a "Blogroll" [0]. This pretty much acts as an aggregator to point you to other sites that might be similar to the author's.

Personally, I've just been keeping a running list in my notes for cool personal sites I find / subscribing to the RSS feed if it has one, mostly discovered from exploring the interlinking web in this space.
