Ask HN: Is it better to use an outsourced commenting system?

Many sites now use Facebook for comments, because everybody has a Facebook account.

For a technical readers, I'd go with Disqus, for a more general audience, with Facebook. (That is if you're playing the numbers game and don't care about Facebook taking over the Internet.)

The advantage of discuss is that it has a common signon for all disqus users so your more likely to get comments.

The disadvantage is that the comments are pulled in by Javascript and are not part of your page. Therefore they won't get picked up by the search engines.

I have never used Disqus so I do not know. I do know that blogs with many readers and large numbers of comments (James Altucher, Mark Suster) all use Disqus. I have read from them on a number of occasions that it is the best. Good luck
