Brilliant!!!!

Andy, you are a frigging GENIUS! And thanks very much for providing this great tool for free! I mean there are apps that are absolute crap and I've paid for them only to delete them later. Just the calculator and graphing parts of this app beats the pants off of everything I've tried so far which is over 25 apps. And I know what I'm talking about. I use a TI-Nspire and a TI-89 Titanium. I just can't believe that I finally found this great app for my phone. :) Thanks again and all the best

Profile Link on stackoverflow

So I've been working on trying to get my stackoverflow account up to 2000 reputation in order to get the dofollow profile link on my account.  I've made it to ~750 so far, and it's a real pain.  That's probably about 10 hours on the site, or 70 reputation/hour.  On the bright side, it has accomplished something else.  My account on stackoverflow has floated up to the 6th Google result for my name by virtue of having so many pages across the site I've contributed to linked to it.  Before this, I had ~100 rep and the result was no where to be found. This in some ways makes having a nofollow link before there a pointless endeavor.  If my account page couldn't make it into decent results for my name, what possible weight could it be passing along to my personal link?  However, it does make the reward for reaching 2k rep even better because in the process you've littered links to your profile all around the site--boosting the status of your account page and thus the link you've earned.
