hehe - this brings back memories
HotM is important to coders here because it is the only type of reward they get. Getting nominated and having a chance to win is a a cool kudos that justifies a lot of the thankless hours of producing free work for others (lord knows the donations button is little more than a pretty image).
In the grand scheme of things - it really shouldn't matter, however it does matter to people and it should be treated as such.
In defense of Chris, I too remember rules in regards to spamming for votes. However saying that:
1- Yes, it should be posted in the first post of the HotM.
2- I think its a dumb rule anyway. Who cares if everyone gets a heads up about it? They can make up their own mind which is best. Its like running for president but not being able to tell anyone :P
Anyhooo. Its a shame another HotM gets screwed. Not just for the one that was removed - but also for the others still in the race. It kind of tarnishes any kind of win - justified or not.
Maybe adopting a BotM approach would be best: Have a month where people nominate HotM. I think doing it strictly on installs is a bit pants anyway.
Anyhooo. Condolences to whoever was removed from the post (been there man

) and condolences to those left in it. O, and condolences to the staff
