.... and by you talking about me I have joined the forum to make a comment
I think it's not much of a secret and in fact a lot of these basic marketing concepts translate easy to the online world. I am very generous with linking to sites I think my readers will be interested in and it has been returned tenfold.
I think online is where generosity really pays off, and not the kind where you only do something to get something back, but the genuine kind.
Make a blog post about all the great people in your niche and why you think they are cool and link to them and I promise that post or webpage will get links back. Not from everyone, but from enough to make it worth it. If you are passionate about your industry you will have no problem finding people to link to.
Thanks for the link.
