There are annoyances, such as excessively poups but it is interesting to try. I have all my bookmarks there, so I cant to change.

Wonderful library tool, practical, and great support

Amazing help with learning and organizing research!

I use Diigo since 2009, to have on hand all the bookmarks of pages I want to keep, for future revisions. Indisputably Diigo is the best.

Fantastic!!

Just awesome!

Excelente por donde lo mires.
Muy útil cuando necesitas sacar notas o apuntes de varios sitios web y no te interesa andar copiando o resumiendo dicha información.
Lo uso en el ámbito académico y profesional. Me da mucho resultado.
Sería muy positivo mejorar la integración con Safari de MAC OS, eso no funciona del todo bien.

Closed sourced vendor lock in. During export they do not add commas into tags, added date, modified date, do not escape < > inside description so totally breaking import into Firefox. During export into IE they do even less. Firefox sites shows it is MPL, but it is not. Diigo does not properly supports Firefox on Ubuntu.

I have used it for over 10 years and it is perfect for keeping and organising information on the web.

good plugin

easy, fast, useful, clean. Great tool to organize informations.

best solution to annotate and refer the web

I've been using this for years now, when the downfall of del.icio.us was on the horizon. It makes it simple and easy to collect a tagged directory of web links, annotate pages or just flag stuff to read later.
