Google Reader + Disqus would be a better Google+ than Google+
plus.google.com
plus.google.com
I much prefer IntenseDebate (still slow, broken OpenID, but moderation is much much better) or Google+ itself. I just wish Google would "plus-ify" Reader already.
Could you elaborate on OpenID issues you are having?
quote: "I think you guys don't get it. OpenID is used so we don't have to create another account, with another password for some crappy message board just to leave a message for somebody."
I struggled for days trying to get my openID working like it was on stackoverflow.com, and I finally gave up. The amusing thing is, I subscribed to that thread via email, and every few weeks, there would be another pissed off commenter who wondered why it wasn't working.
Does your openID require setting up a local account (with username/password) still?
However, if you want to install our widget on your own sites or become a moderator you will have to create a Disqus account. Mainly because we need to verify those accounts via email.
Hope that helps.
We serve all our static assets from Akamai, and there's only a single dynamic request per embed load (that's also cached). My own benchmarks show Disqus loads in under a second on most pages.
