I have a proposal. What if you could enter the URL of your blog(s), and that way any self-submitted content would start at 2. This would encourage more people from HN to write and answer comments, and would hopefully make the site better overall.
And probably you wouldn't be allowed to do this until 30 days after creating a new account, or else there would be some minimum karma. Or perhaps your blog needs at least 100 karma on its own before the URL is accepted. Either way, I think it would generally make the community better if some variant of this were enabled.
I find the most interesting content (to me) comes from sources I don't already read and follow. If a blog comes up twice or more on HN, I'll have subscribed already (assuming it's full feed and is only updated occasionally - blog interestingness is inversely proportional to posting frequency IMHO).
