You noticed that I gave it a Thumb Up. I don't remember the exact percentages or base numbers, but CodeProject.com with 8,800,000 members had 32,000 members online or ~ 0.4%, while we had 57 online out of about 180 or ~ 31.6%.
I don't know how either site tracks membership (I know that several CP members have not posted since 2008 so the membership could be a highly inflated number) or the number online (if someone logs on "forever" is he constantly considered as logged on, or only when he is active). So, yes, figures don't lie, but lyers figure.
