Twitter Grader is a web app that allows users to obtain a “grade” or score out of 100 that measures the “reach and authority” of a Twitter user.

Features:

• displays statistics about searched Twitter users (rank, following/followers, updates)
• displays grade /100 on searched Twitter users
• suggests other folks to follow
• keyword search feature

The Good:

Twitter Grader has a great UI and produces results from searches quickly (two or three amusing “bon mots” are displayed while waiting). It will let you know where you (or any other Twitter users) stand in the big picture, and allow you to find others who share interests, ranking or keywords. You can also tweet directly from Twitter Grader to other users letting them know how you found them, and you can publish your own grade via tweet.

The Not-so-Good:

As for functionality, Twitter Grader is great. Our only complaint (and it is a very minor one) is that the whole thing is shrouded in mystery. How does one figure out the grade anyway? Over the course of an hour, our grade went up one point and we rose about 10,000 in overall ranking…
