There is Competitors for different hardware (might be Maemo though) and there is Alternatives for different software for the 770/N800/N810, with sub-categories. It makes sense someone is afraid the latter will evaporate from Talk because these (sub-)forums are not directly Maemo-related. However, there is no complaint (unlike the Competitors forum & threads), so why bother to remove them? I don't think that will happen.
