Too few sampled comments (1) to say how often HN recommends it.?

Why HN links it

A bare link to a Show HN project page for Highfive, an app that turns Twitter into a news aggregator. No commenter discusses the writing.

Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

    I actually wrote a blog post on regularization a few months ago. I think it covers some of the issues, like overfitting, glossed over in this post: http://acompa.net/on-regularization.html

    Agreed, I'd be worried too. I actually address the spam thing in the Terms section ( http://acompa.net/highfive/terms/ ), and I have a little example in the How It Works section ( http://acompa.net/highfive/help/ ). Guess I should make those more obvious?
