In this question (where the topic includes the word "BitCoin") eMansipater writes the following in regards to capitalization:
The capitalisation thing is my own arbitrary convention to differentiate the technology (BitCoin), the open-source client (Bitcoin) and the unit of currency (bitcoins)
I believe that this is way too complicated and that it's better to stick to one way of writing it. Especially the "BitCoin" version seem unnecessary. I would like us to be able to quickly edit topics that use "incorrect" capitalization so that the site looks clean, but then we have to decide on something.
Please write you suggestion in an answer and we'll let the votes decide.
