I think promoting a bar on the forum is good for the bar and good for the forum itself in terms of traffic, I think over on the other forum, the two most popular threads are both bar threads (C&D and Sensations). Speaking with my neutral hat on, I think it's good you've managed to get an exclusive on the Nana Go-Go's as something different.
The basic format for a successful bar thread, a few pics of the girls here and there chipped in from the owners and the rest can take care of itself. Sensations and C&D threads probably more so because Scott and Jim are on the ground and are able to provide constant updates of what's going down. Some bar owners aren't in Thailand for the whole year. Where a lot of guys are stuck at home for X amount of months, conversing with other patrons of that bar and management within a bars thread, acting as a substitute for perching on their favoured stool at the bar.
Look at Amy/Emmas bar that opened recently in Walking Street, a total PR disaster. Word of mouth only got out a couple of days before opening so only those on the ground got to know about it at the 11th hour. Contrast that with how Vinnee promoted Fantasy Lounge, with lots of build up to the actual opening of the bar.
