Which type of websites do you book mark? How do you manage the folder?

Personally I use Firefox. Along with the bookmarks tab, I heavily use the bookmarks toolbar. In the toolbar I usually have 3-4 folders set up. Forums- Has all my regular forums and written knowledge sites like this Games- Where I have all my skill gaming sites Social sites - Where I have myspace,facebook,ezihippo profile page, along with quick bookmarks to check up on recent posts of mine, which I delete from time to time. Sports - Changes per the season, but I luv fantasy games. Then I have some handy calculator,FAQ(like html coding) for quick references. Then my actual bookmarks tab has several more folders Check back- Where I put any quick links to check up on l8r in the day L Check back- Where I put newer sites online, I tend to check on 1st and 15th of every month, to see if site is still around, paying,active etc. B4 I join. Online $- Where I store FAQ/guides to anything related to making money online, like hot-to drive traffic to website, using search engines better and that type of stuff. WTB-(want to buy) Where I put links of stuff I wanna own,basically a long term shopping list Poker- all my poker links go there
