exogeny said... The percentage of links to your blog that you post in your comments is extremely high and extremely notable. Make of that what you will.
HN uses rel=nofollow links so he's not posting links as part of some SEO plan. Cursory review of his previous comments shows he links to other sites more often than his own. It makes sense someone would often post links to their own blog though - if they're interested in a topic, they're likely to both comment on and blog about it.
Beats users linking to one of the near-web-monopoly sites like twitter or facebook constantly!
I'm shocked you're essentially chastising someone for having their own domain and publishing articles on it they then link to. If anything we should be encouraging this behavior.
