I'm not totally sure what "organically spreading" really means. People organically coming across your work happens occasionally, but it's going to happen a lot more if you put it out there.

I have a (really average) modicum of success with my writing. I managed to live off it for a month or so after my book release, but that was about it. It's going to be a passion rather than a main source of income for a long time, and I'm okay with that. I've picked up writing jobs here and there, ones that get me actually published, but they're all pro-bono/volunteer, which I'm okay with because they hold the promise (well, one of them, at the very least) of paid work sometime in the future, and it's writing that I enjoy (I mean, reviewing albums I love is something I do anyway, the only difference is that the published works are slightly more formal/polished).

But I guess it's not really about the money.

The best way, I think, to get your work out there (aside from pandering to specific markets, etc... I'll stay out of that area...) is to maintain an online presence. It's something I write quite a bit about in relation to music, and working with live bands once a week means I see good and bad examples of it all the time. Some acts, the ones that tend to do well, are, at the very least, really active on Facebook. They post at least once a week. I see others who haven't posted in 6 months - not even the fact that they're going to be on live radio that very night. The link between activity and success isn't a totally solid one, and (at least, in the music biz) having a Facebook alone but no soundcloud/bandcamp etc isn't enough, but it certainly doesn't hurt.

Having that presence is going to make you connections, too - something I owe a lot to. My small-time (again, volunteer) radio job I owe to knowing people, and now, knowing the boss I have here has helped so much. I got to go to a pretty darn big industry, invite-only event earlier in the year at which I met even more people. In terms of writing, I went along to an event/panel at the city library last month or so and did a really quick, shoddy write-up of it, posted it on twitter, Facebook, etc, and it got retweeted and commented on by the library, librarians, local writers, those who held the event. I'm friends with a few of them now (not close friends, to be sure, but the sort of friends who I enjoy talking to simply for talking to - and they have the benefit of being in the industry I want to be in). The publicity of that post brought in a few readers, and even a few who went back and read a bunch of older posts.

Hell, I have a hubski-related example: after talking here about radio work etc, I got a message from ButterflyEffect asking if I could get an album on air here (I'm in the process of trying at the moment, and at the very least I expect to be able to pass it on to a few hosts) and he sent me a digital copy. After listening and enjoying, I spent literally five or ten minutes writing something really short about it (I was exhausted and had some time to kill in the middle of a really long day) and posted it to my blog, sent it to him, etc. His publicising that mini-review brought in a reasonable amount of traffic (thanks for that, by the way, BE).

Social media is a huge advantage. I let slip every now and then, but I try to stay active at least on twitter, and to write and post something at least every other week, and it really is worth it.

So, yeah, what TNG said: take advantage of any avenue you can find to share what you have. Alongside that, keep up a profile that isn't just your writing - there's no guarantee that people who enjoy what you as a person have to say will enjoy what you as a writer produce, but usually there's a lot of overlap, and people are obviously more likely to check out something if they know the person who made it (as Floatbox said).
