At least that was my experience with Pocket. Maybe it works for some. I do the same thing with physical books. I don't keep a list of books to read. I keep a bookshelf full of stuff I'm making my way through over the years. Spending the money forces me to choose what I actually feel is important I read vs what I think I want to read.

It'll save them to a single page that includes all the previous tabs you've saved so you can cmd+f it if you REALLY want to find That One Thing You Had Open That One Time)

Accumulating tabs works for me. I always end up working back through them because they are so visible.
