Hi, thanks for your response. The goal of this would not be to stop you opening more tabs but, to help you manage those tabs. Kind of like Dropbox for tabs, I think. Would you be interested in using something like this?

Yesss but there's lots of apps like that do similar / overlapping things that you'll sort of have to steal/borrow from. In particular, some form of social bookmarking/tagging would seem to be a necessary component of a service of this kind.

The trick then is to pull this off without drowning in your own web of complexity.

Thanks for your response. Some people have tried to tackle this problem but, I feel it can be done much better and as you said, incorporate some kind of social elements.
