I have briefly introduced the problem here. Personally I really prefer the word ‘purchaser’ to ‘consumer’. So I think I will choose word ‘purchaser’ as my standard on this website.

Against this choice I thought that the word ‘consumer’ can help to easily distinguish the ‘consumer market’ from the ‘B2B’ one. Both a businessmen and a consumer can be purchasers. However I do not think this will be so important here on my website. My way of thinking is much more philosophy oriented than business oriented, so I think the word purchaser will be a better choice for me, because it remind me of a different dimension of the act of buying that is not just consuming something, but also caring it.
