The only things I re-visit are reference websites, which I could easily find with a quick search.
I really do not see why I would want to save 1000+ tabs, at that point I might as well just search through my browsing history.
I added some features to help people keep their saved links organized, so that it would be easier to parse them at a later date. You can of course just search through your browsing history, but all of that data is lost whenever you clear your history.
Even if you do refrain from clearing your browsing data, there aren't many options for organizing your browsing history. What if you want to view every link you've ever saved from Ycombinator? What if you want to find every link you've ever saved on a certain day of the month? Also, what if you want more control over which tabs are saved? Have you ever had so many tabs open that Chrome no longer displays their titles, making it extremely difficult to find the specific tabs you want to save?
These are the sort of problem sets that I set out to solve. Hopefully there are some power users here who are able to derive some value from it.
Give it a try, it's free.
