In a lot of ways, my open tabs are my to-do list. Some of them are things that I need to do, some are "I want to read this article when I have time", some are long term research.

I've tried doing things like bookmarking things to read later, or saving them to Evernote or Instapaper or whatever, but I never went back and actually read them. Ever.

So, this workflow actually works for me, even if some people would consider it unwieldy. It actually works pretty well, until Chrome starts getting annoyed. I probably average more around 120, but I've got a couple of projects happening simultaneously right now, so I'm up around 150 at the moment.
