I know... it's hard to believe how active and alive the old WOA was. But I know this version is even better and will eventually take off.
I think bringing back the online status and adding a Who's Online page is a great idea. I know privacy is a major concern these days but personally I wouldn't mind having it on by default. After all it's not like it's a major risk for members to know who is currently online. And would be encouraging to see who is online and active. But maybe that's just me. I think it's a fun idea though no matter what route you choose to take.
