It could be no harm to give a weekly public talk in a venue that has good foot traffic.

The local public library has such facillites available, as meeting rooms and such.

A person then could then give talks to the public on subjects as diverse as
"War and 9/11: why hasnt anyone been arrested yet?"

"The Global Money Power"

"American Liberty"

I suspect that with publicity and good theater production (and a number of performances) that one could attract a steady audience.  Getting on the library calender of activites is one way to get your name out, our local library mass mails its monthly calender to every house in town.

I think that one could also tape his sessions to improve his performance.  Post good ones on tube or other vid sites.

Who knows, you may blow up and become an internet celebrity!
