A fellow blogger wrote a comment to me a few days back that my link to his blog is pointing to my own blog. I checked, and indeed it was true, and not just his link - a lot of links didn't work.
After some research I found the culprit - my online blog tracking service didn't write the urls to some of the sites for some reason. I emailed them, and got a very quick response (considering) after 3 days!
Thank you for the bug report. We believe we have corrected the invalid URL problems you reported and regret any inconvenience this may have caused. Should it happen again, please let us know."
So now I can relax and apologize to any of you who didn't get the proper link-up that you deserve. And I can still recommend bloglines as my favorite online rss reader and blogroll provider.
If you are interested in other things I am reading (beside sharepoint blogs), check out my bloglines share and enjoy.
