With more and more alternatives appearing to Lego which also increase in variety and even surpass at times Lego quality, why focus just on this company for a brick building community? I for example have been badly burned by Lego’s handling of the Mindstorms brand and there are more compatibility broken product lines from Lego.

Is posting other brands alright here? Will it lead to unpleasant conflicts from Lego, if their brand name is used?
