Honestly, I find signature advertisements distasteful, and it is not impossible that I will someday ban the practice. However, it's obviously an important part of the forum ecosystem today. So if you use signatures for advertising, what are your suggestions for forum improvements in that area?
For example, one idea I had was to allow users to subscribe to campaigns that other users set up, and then the campaigner could automatically push signature updates to everyone subscribed, and also track exactly when and for how long each user was subscribed. Would this be significantly useful? I'm not all that familiar with how these signature campaigns work, so I'm not sure.
However: the forum will never intermediate these transactions. We will not touch the money involved or perform any sort of "screening", etc. Also, I have no particular desire for the forum to take a cut of sig-ad transactions.
(I'm probably not going to implement anything in this area very soon, but the matter has been on my mind lately, and I wanted to see what people thought.)
