Hi Glenn,
You ask a great question, but be careful.

You don't want to waste too much of your
time, if you're thinking: marketing.

Of course as a gardening enthusiast, by all
means visit some of the sites I'm showing
below.

But I believe in getting easy and instant traffic
in a substantial way.

I recommend marketing in social sites with a
Google PR of 6 plus. This way you're sure of
reaching millions.

With that said, here is my source for tapping
into smaller niche social networks.

Hope you find these useful.

God loves you.
Unk Brent.

P.S - I'll soon be releasing a "Down and Dirty
Instant Traffic" course. If you're interested,
I'll share signup details.
