Top Research Tool Rated 5 out of 5 stars

In frustration, I was about to write my own web page markup tool when I wondered if anyone else had tried it. A little research turned up Diigo. Their product topped my own plans and I found no reason to reinvent an excellent wheel. I give it top marks for one of the most useful tools ever.

This review is for a previous version of the add-on (5.1.0.29).
