I find myself staring at the Google search bar, I try to be creative with new things to look for. I'm not a creative person and have no artistic bone in my body, I always end up going to the same 10 or so websites. Save me from the mundane of internet.
-Reddit
-Pandora
-Twich
-Youtube
-newegg
etc. obviously this website. Stay classy Tek Support
The only bookmarks I use are for my email(s), a couple tech-related links, and school links.
I don't have bookmarks for YouTube, Newegg, TekSyndicate, NCIX, Amazon, Google, or anything like that. My address bar autofills most of the websites I go to, and if it doesn't I just type it in if it's short than 15-20 characters.
I, too, have a lot of bookmarks. The tagging system in firefox really helps keeping the stuff organized. I tried it with folders but man that didn't work out.
I have some bookmarks (20-ish), but I generally just use autocomplete to navigate because it's faster. Ctrl + T, t, enter gets me to Tek Syndicate faster than anything else.
