I use delicious and foxmarks both since I tend to use multiple computers daily, not just one “pc”.
My delicious links are at:
http://delicious.com/contentpersephone
My tags that would fit the question above are probably: news; blogs; alternative; activism; culture; and politics. There is a fair amount of overlap between categories.
Some links I frequent very regularly - others only sporadically. I tend to keep stuff on delicious that I want to save long term, and use the foxmarks more for “pending” links.
Also, my “local” links on delicious are set to private - not shared - for privacy reasons. (Those links have mostly already been mentioned here: scroohoo, hangover journals, and mx, of course).
Additionally, I use google reader for skimming current news and tech stories.
I used to frequent Asheville Mamas regularly, but it became it bit too much to sort through everyday and I now only skim through once a month or so.
Clearly, I spend too much time online.
I would also read that column, Edgy Mama.
