This can also mean that if people adopt FPGA instead of ASIC, then there is room for scamming bitcoin miners who invest in FPGA based miners.
You bring up a good point, whilst BitcoinTalk is primarily focused on BTC, what is to say that a company selling GPU Rigs (such as ours) or FPGA systems would ship products specifically to clients on this forum, but then if someone ordering a GPU Rig for mining of Litecoins, they get ripped off if they are from another forum, or not members of this or any community?
A full list of companies providing FPGA, ASIC and GPU systems is what is needed and community members here need to be able to add their feedback to the list as do the companies listed in a public forum, not behind closed doors (PMs) where literally *anything* could happen.
