uncle bill suggests that it might prove to be difficult to compare Eris and Loki, as the only thing they really shared was a penchant for causing trouble.

I haven't given it all that much thought, but I did find this with a quick google:

Actually, [Loki] does have many other aspects in common with Eris, including bad puns and mental masturbation.

so it looks as though I could expand this to a comparative study of Loki/Eris/AWADtalk.
