I noticed a steady increase of page views lately, so I am currently considering to turn on blog commenting (hey, I didn't really know someone was actually reading all of this ;-) ). I would really like to see some feedback on certain articles (e.g. someone might want to disprove my "IP packet fragmentation"-theory). On the other hand, blog comment spamming is quite a problem, and tends to obfuscate legitimate responses. Blogger.com allows for commenting of registered blogger.com-users only, but that would limit the group of annotators considerably.
I will probably give it a test run in some days. Please stay tuned.
