Why not?

I registered my blogs at Technorati, I signed my posts on ScienceBlogs with a link to my Wordpress blog, and I posted regularly.  And to my surprise, people started showing up.  Only two people have posted comments (interestingly enough, on my post about Technorati).  Both of them are people on whose blogs I have commented.

It's nice to know that someone is looking at what you have written.  But you really haven't had an impact until someone has linked to a post of yours.  Will it happen?  Maybe someday.
