to help manage this i created a "speed dial" extension and use it basically as a visual bookmark manager. the advantage to tabs in a list is that they are easy to reference visually, and like any bookmark can be sorted and arranged into folders. for example i have one for technical references, various research topics, etc that i plan to come back to. and its easy to pop one off the list to maintain them. check it out if youre curious, its open source!
