More than bookmarks Assegnate 5 su 5 stelle
Pearltrees is a perfect tool for me and the way I use information, think about subjects (I have A LOT) and organize them.
Quasi mind-mapping with the ability to curate, annotate and find similar from other dedicated users. Since users are global (company is in France), you will have a better chance to find stuff that the big search engines ignore.
One of the few apps I pay for.
If you go Premium, you can do more than comment on a link. You also can make trees private. Best yet, you can preserve that page in case it disappears.
I can't stand linear bookmarks because that's just not how my mind works.
