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.

The real question that I want the answer to is – how do you manage to remember those 128 different usernames and passwords?
For a while I took a two-tiered approach to password management.
Tier 1 – mission critical apps. such as school email, Desire2Learn, and about 5 -6 others: These are strong passwords that are changed every 90 days.
Tier 2 – all the other stuff (most of the 128 tools you refer to) was a simple password that I have used for years. However, since some of these tools have become more and more important to me, and as the amount of account hacking has been on the increase, I have been converting them to strong password as well. The password formation follows a system that makes it fairly easy to remember them.
In other words, I just make it up as I go. I keep trying to use OpenID but keep running into roadblocks. Right now, my own system works better than that type of solution.
Sounds exactly like my method (except mine is 3-tiered). Only, when I decide to change a password, then I can’t remember all the places I have to go to change it. And this leaves a trail of older passwords behind.
P.S. Sites that restrict password type (must be only numbers and letters, must have a capital letter, etc.) are nightmares for managing passwords!
