why not make them pay a key per week for being excempt from unlisting?

Yeah, its a little bit like a 6 pound fox fighting a 600 pound gorilla.

On the other hand bazaar is doing some things overcomplicated - can someone tell me why bazaar has two keys, one which is worth one key (sic!) and the other is worth 2.88 refined? Both are seperated entities in search also... like they never learned the hard leasons of 7 different kinds of keys from tp... And what does the small star in the top left? Where is the 600 pages printed manual you need to understand "sell now" and "buy now"? Why is there no "AND/OR" clause in search, why is the default search behaviour "AND" which renders most searches useless...

Seriously, I am not sure who is the 6 pound fox and who is the 600 pound gorilla in this duel. Maybe it is also a duel between a 600 pound fox against a 6 pound gorilla or something like that...

comparing tf2outpost to bazaar I see several features missing like more than eight items per trade or maybe a number towards every item and partially automated syncronisation backpack-2-trade so you see if a trade is already done. Also bazaar got pretty much rid of days old orhpan-autobumping trades by requiring the user to be available to display his trades.

comparing bazaar to tf2outpost on the other side shows bazaar is lacking something fundamentaly important: users.

the key market might crash some day. but not til next thursday and most likely not this year either.

If keys become economically bulky for trade other items will start taking their place. This is already partly happening with Tags, Gift Wraps and Backpack expanders.

Keys are already overpriced in comparison with these though "only" by 10-30%. At 50-100% we can talk about "crash imminent".

All-Bump wouldn't do anything bad which people aren't already doing. It would just make it easier. Adding some random seconds to each bump would also avoid bumping too much at once.

All-Bump would remove most incentive for scripted Auto-Bump without giving non-donors any tactical benefit.
