I just added a
links page
to my site!
Plenty of others with personal websites like to link to each other with "buttons". These buttons are 88x31 pixel images that act as an ad for their site. A lot of how this personal website sphere is held together is by people linking to each other's sites using these buttons!
Everyone I link to also links to others. And in turn those people link to more people! You can traverse the personal website net this way without the need for any sort of aggregator or index. It's like getting in a wikipedia click hole! I've only added 3 sites for now, but I'll keep updating it over time.
Go check it out and get lost in the net :)
