I don't know if it still exist, but it could be nice if there was a website or an app that give some info about BC adress, like top 100 BC adress, but more focussed on news adress. I could tell us how many new users we get everyday.. etc. It would be good to know especially now right before june 1 so we can know if the coinkite is doing some good effects.
http://bitinfocharts.com/ Has some good info. Wallets over 1/100/1000/10000, active wallets last 24 hrs., link on top for 100 richest addresses, etc. Seems reasonably accurate with a bunch of coins that can be toggled on,and off for comparison.
