What do you think is better while advertising?
1) Making a fixed campaign with 0.2 per month for 5 best quality posters, min requirement only 20 posts , so something like 0.01 per post.
2) Advertising in bitcointalk with banner ads, with only one slot for 1btc per month.
IMO signatures are better because you get better visibility.
Just curious, do you want to make your own signature campaign? 0.01 per post rate is too high in my opinion, but you could limit the maximal post for that, like 10-15 posts per week. But from your both option, I prefer signature campaign instead of banner ads.
