Time has been very thin of late. In the past six months or so started noticing an increasing number of links from del.icio.us and started pulling the feeds of some folks I like to follow their reading list into my site feed aggregator. I had about four or five del.icio.us feeds in my aggregator (meta aggregation of other's meta aggregations - MetaAg MetaAg). This past week I was taking medicine that tweaked by sleep patterns so I had some free awake time after midnight and I finally set up my own vanderwal del.icio.us feed.
I like having the ability to pull [meta] tags aggregations that others have used, like security, which is a great help during the day at work. I can also track some topics I keep finding myself at the periphery and ever more interested in as they tie to some personal projects.
I did consider something similar with Feedster, but it was down for updating recently when I had the tiny bit of time to fiddle with setting something up. By the way, Feedster is now Standards-based (not fully valid, but rather close) and it loads very quickly (most of the time).
