I wouldn't worry about it - on the contrary it might even bring a little (probably worthless) traffic.
In fact, that's how I found HP - through a link posted on my local craigslist rants and raves. Responded to the hub a few times, joined and posted on the forums a few times and finally wrote a hub. And I was hooked like a fish.
I don't understand the difference between worthless traffic and what would be the other traffic? I thought all traffic was good. When Spyker was going through transitions, my traffic went through the roof - was this worthless traffic too? How do I know the difference?
Well, it actually depends on your goals. If you just want to be read, any traffic is good. If you want to make money - some traffic is better than other. Search engines traffic usually is the best in that regard.
Worthless traffic is the kind that does not commit to sales on a person's blog, affiliate links or any other way that's going to produce results that will eventually make you money. But if you simply want readership, then any traffic is good.
