What's the current bounty?
Make sure the bounty is in escrow before you put in work that you would regret having done for a disappearing site. tosaki currently seams to have severe issues holding him from being responsive and act reasonable concerning bitmit.
I feel a bit sorry for bashing him and his service together with others here as I, too would love to see bitmit take off. I really see how this could happen and I'm sure many people would be very willing to help on that. Even making bitmit open source would have more potential to help bitmit.net flourish than it would to feed the competition. I would gladly help to implement the features that I so far only nagged to get ASAP(!!!). Also I guess monetization could be done much more efficiently by charging for the listings 5% of the starting price and limit listings to 10 days. This way you get more low prices and get demand from snipers to the site. People wouldn't disappear having their overpriced articles re-listed indefinitely spamming the site with crap like now.
Cheer up Tosaki ( which tosaki?)! You have a great product in your hands. If you give up for good, others know they can take over. I guess that is the main reason why many try to force you to a decision. Don't take it personally.
