Self-Promotion-- Looking for opinions from local comics.

Self-promotion...is it for the vain or is it a neccessary evil?  I'm wondering how the local Reno comedians are handling the idea of self-promotion. 
Are you handing out flyers for "open mics" or are you just letting people find you through word-of-mouth? 
If anyone is practicing self-promotion, have you seen an increase in your audience, hits on your web pages or You Tube channel?

Do you care if people find out about your ideas, or do you do it just for you? 

Comment and let your words be heard.
