As I’ve explained in earlier pieces, I periodically post “most popular” lists of websites that I think educators might find useful. Of course, there are a number of ways to gauge “popularity.” I just view these lists as opportunities to check-out some new sites, and find it interesting to see which ones might be particularly “popular.”

Today, I’d like to highlight two tools (I’m sure there are others) that show what sites are being bookmarked by Delicious users during various periods of time.  They both are also on The Best Places To Get Blog, Website, , Book, Movie, & Music Recommendations list.

Popacular shows the top twenty-five bookmarks from Delicious.com for the last: hour, eight hours, day, week, month, and all-time.  At first, I thought it wasn’t going to be a particularly useful web tool. However, I checked in on it three times today and found two very helpful links.  I probably spent a total of less than five minutes looking at the site.

Wectar  not only has  a continually updated listing of the most popular Delicious bookmarks, but with one click of the mouse it will then show a list of related websites, including “thumbnail” screenshots.  Plus, you can identify the most popular bookmarks by categories, as well.

Delicious, the popular “social bookmarking” tool, has just added some neat features. One is a page where you can see the most popular websites at any given moment. I’m adding this new “Hot List” page here.

Feel free to share other suggestions.
