As far as spreading your writing without shilling it around, it can be tough... No doubt. It's hard to get people to read things these days, but make no mistake--there's an audience for just about anything out there. The hard part is finding the audience.

To be honest, I'm working my ass off to get published right now (while working through school), and while I have a blog, I don't update it much as I spend most of my time working on my novel. However my best advice is consistency. On the blog you have now, keep pushing out content on the regular. I have a few friends who started blogs from nothing, having no readers but me and their girlfriends and now have regular readers. It's mainly a matter of persistence and perseverance, keeping your site fresh is huge. Over time, people will start to recognize your work, although it may be very slow. Just gotta keep working hard to improve your craft and you will find an audience. Find what your 'niche' is, and cater to it. For example one of my buddies is a writer but he loves typewriters, collecting them as a hobby. So he posts pictures of his collection along with his work and he has gained a nice readership.

And as thenewgreen has already mentioned, use the avenues available to you like reddit, Hubski, CritiqueCircle, Absolute Writer's Watercooler Forum... There's tons of sites out there. Hell, I just started posting my work to this site and have already gotten some good feedback.

Also, I'd be down to participate in a podcast on writing. It's not just my passion, it's my life... And I love talking about it with others. And your podcasts are primo dude.
