Is the stack alert twitter bot service still on? If not is there a similar service out there any where...?
Stack Trilogy seems to be doing the same.
Hello, I had the idea, then ceded it all to @teifion, who had started @so_agg before that (@stackalert was just a cooler name). I reserved the domain name and stuck up a page, just in case we hit the jackpot. It will expire in February 2010, if I remember correctly.
I subsequently gave up on Twitter completely, and didn't have any further contact with Teifion, though he has been on SO fairly recently, and has an account here too. So I have no idea if it was blocked, or he stopped, or something hung somewhere and he hasn't been to see why.
