I dont know what is the clickthrough rate of twitter tweets, but the payout rates were thought of by the following logic:

Banner CPC cost 10,000 satoshi/ click, on average, best rate is on mellow ad with 8000-9000 satoshi /click.

If 1 twitter user has X followers, I assume the normal impression/click ratio applies to it, which is 1% to be conservative.

Therefore I assume if somebody has like 1000 followers that means a 1% CTR, which is 10 clicks.

Therefore, that costs us a 10,000 satoshi / click normally, which would be 100,000 satoshi.

Well, with the twitter campaign I pay 2000 satoshi /click, which means that it's 80% cheaper, if the 1% hypothesis is correct.

So for example 10,000 real followers 1% CTR gets 0.002 btc.

Now if it's say 0.5%, then it's 40% cheaper.

I am not sure how efficient twitter is, but it can't be that bad, given that we only consider real followers and not bots, so in worst case scenario we still need to get a 0.5% conversion rate.

And then it saved us 40% cost, not to mention we get to popularize hashtags, **and with some luck we could go viral from the network effect, who knows.**

So I am now confident that this marketing method is the best we have yet.

Lemme hear your opinions.
