I go offline for days at a time. First, open every webpage and document I think I'll need to finish The Big Project. Then disconnect and work. Stay offline* until the project is done. If projects are overlapping, hitting 300 tabs is easy. I also have several gigs of saved PDF and HTML files, but one-off information goes in a tab. What good do your "online utilities" do for someone with inconsistent internet? * Maybe every three hours I'll connect for a few seconds to check for voice/email.
