Should I list the journals/conferences that I have reviewed for in my personal website? I have been thinking about this question for a while now. I could see some advice in a.SE1 and a.SE2 that answers for the inclusion of such activities in a CV.

However, is it a good idea to list such details on my personal website?

My present webpage does not contain my CV -- It just lists list of publications, projects, and some stuff like academics backgrounds. And, I don't want to put my CV later either.
In general, People's websites tend to be less formal and more detailed, so I say go for it, especially because it shows some more well-roundedness and "giving back."
