I use the bboah to look up old hardware that has been out of production for almost 20 years or more. Hardware that I would have used with my A500 or A1200. The site is invaluable for such a purpose, as there is no other resource out there where this information is available.
I would say that adding newer hardware is fine, but more often than not, there are plenty of other resource sites for this information as a duplication of effort in this regard seems a waste of time... That said, it's someone's hobby, let them add what they want... But be mindful that if the main reason or someone using a site becomes difficult and slow (hosting storage and bandwidth charges might go up etc), the majority of users might move on... you could be shooting yourself in the foot.
