Kiruba and Codey point to this interview about PR & Blogging. Though the article is meant for large companies with minimum online presence, even small projects can become PR successes using blogs. I've made so many friends on the net by just searching and reading rants/reviews about blogsnob and then commenting on the blogposts.

Also, I think blogging teaches you how to communicate more effectively and cleanly. For instance, we got this email some time ago from an AdSystem customer:

This program doesn't appear to do what we need... Can you please let me know if this program will do what we want and if not, how to get a refund.

Though we did solve all the customer's technical problems instantly, and with ease, I am sure that the way I communicated helped a lot, and I owe a lot of this to blogging regularly. Here's what we got from the same customer in the emails that followed:

Thank you so much for your quick and courteous response... I sincerely appreciate your help and if you ever need a testimonial..., just let me know. I'll be happy to write one for you.
