Blogger-specific feature post

I would like for the blogger to have like an "about me" blog post (like a biography field on steroids), that will be shown on their personal blog page, but not in the site-wide blog listing. Any ideas how to make this possible? I see a few possible tracks, but can't figure out any of them:

1) If it's somehow possible to filter a featured blog listing by who featured it? Then the user could feature whatever post he/she would like as about-me page and I'll just show latest featured from the current author.

2) If it's possible to exclude a category in the site-wide blog? Then the bloggers could simply post to that category (e.g. an 'about me' category) when they want to create a post.

3) Extend the user profile registration with an 'about me' section with a few custom fields. Will give much less freedom to the blogger though.

4) Manage the 'about me' in a totally different component, like Zoo, Joomla native or JReview, with the downside that the blogger is introduced to another publishing Ui, which I would like to avoid.

Any suggestions on which direction to go?

Thanks!
