Bookmarks

I've chosen Diigo web page (https://www.diigo.com/index)  to create my own bookmarks for several reasons:

• simple and accessible interface
• you can create not only new bookmarks, but also notes, PDF and images
• It is free and you can log in using your Gmail account
• Unlimited number of bookmarks
• It offers a mobile version as well 

My  most frequently attended bokmarks are ⇓⇓⇓⇓

In addition I would like to say that I have never heard about such  web pages for creating bookmarks, and it is amazing that now I have an opportunity to ease my Internet surfing by making personal bookmarks . Thank you for such a great recommendation ;)
