This is in reference to this question in which styleguidance.com talks about their site promotion ideas. http://meta.stackexchange.com/questions/3281/i-decided-to-do-a-huge-promotion-to-promote-my-site
They list several ways for their users to enter the giveaways from tweeting certain things on twitter to 'liking' posts on their Facebook fanpage. I'm interested to know if all of these entries are manually tabulated for every giveaway or is there an automated system in the background keeping track of the entries.
If it is all manual....how could it be automated?
