Who’s reading whom? Bloglines redux

It’s all about you, baby.
Or, it’s all about me.
Every technocrat and blogger know that one of prime behaviors fueling blog indexing and search is the impulse to see who is linking to and/or talking about you, your blog, or your company. Blogger’s watch lists –tracking who’s linking to you–are core to Technorati’s future business plans (think of them as the latest form of (non-corporate) data-mining, aka market research) and popular as well at Feedster.
A number of bloggers now check OPML files and RSS aggregator data to see how many readers–and who–subscribe to their feed. Richard McManus of Read/Write Web has written a couple of posts about this, including a recent one that discusses how the number of B loglines subscribers to a feed can go up–even as the author’s postings go down.
( Kellan, one of the commentators, remarks: “One explanation for Seb and Mark’s subscriber totals increasing is the growing number of people who are switching to Bloglines, and bringing a long OPML file with them. I’d read the increase as largely driven by Bloglines growth.”)
Conclusion: If you interested in blog data and metadata, Richard’s post is worth a read–as is his blog, for that matter.
Side note: I looked up my own blog and list of public subscribers, and was interested(this is complete navel-gazing, so be forewarned) to see a) how many of the people I knew or had met, and b) when various people had started subscribing to the feed.
The answer to a) was about 25% are known to me, and b) there seem to be more folks added in the past month–though that is probably linked to the growth of Bloglines.
