Here's a quick way to get some basic data on 10 Twitter users (Tweeters) including a "Grade" from Twitter Grader. The grading interface was inspired by a request from DrVes and the basic data part was requested by Laikas - so I put the two together to make this simple spreadsheet. Note that it uses the ImportXML() function to grab data from twitter.com and from twitter.grader.com - so it goes right up to the limit of 50 importXML requests (which is why this sheet only allows 10 tweeters at one time).
