I used the Web 2.0 Quotient calculator created by Manish Mohan and came with a score of 100. It appears to me that you can score a maximum of 116 if you are at the max on every category.
After calculating my score, I took the time to update my list of free web-based tools on my PLE page. I now have accounts to use 128 different Web 2.0 tools.
