Have you heard about coworking?

To learn more about coworking, check out this article: http://www.nytimes.com/2008/02/20/business/businessspecial2/...

If you're interested in the concept, find a Jelly near you: http://workatjelly.com/

You can also read more at the coworking wiki: http://coworking.pbwiki.com/

I think you should go to a Jelly. Seems like it would an especially effective way to alleviate "boredom" you are experiencing, which may not be stemming from the work you're doing, but rather just the lack of social interaction as a result of working very hard by yourself for an extended period of time. At a Jelly, you are working "by yourself," but amongst others.

Also, if it really is the marketing-type work that you find unsatisfying and boring, going to a Jelly will possibly help you find a cofounder/designer/marketing-type person with which to team up.
