Not a good practice - It does more harm than good.
Don't join such campaign! I've decided to stay out
of it entirely.
An interactive experiment has been initiated recently
by Dosh Dosh to exchange Technorati Favorites.
I'm a participant of this exchange campaign.
This exchange is open to anyone who owns a blog.
Please follow the following procedures if you're interested
to take part :
1) Fave my blog by clicking the Technorati "Fav This Blog"
widget located at the right-hand sidebar near the top.
2) Leave your Technorati username as well as a similar
link to your blog in a comment. My Technorati username
is "schee88".
I'll add your blog to my "Favorites".
You can get a better idea of this exchange program by
going through Dosh Dosh's post.
