Simple .NET CMS with following features?

I am going to be posting some kinds of 1)articles and 2)my program related faqs on my site and would like some centralized CMS (with WYSIWYG html preferably but not really too important) for that, also support of some openids would be preferable, I am not sure whether they come w开发者_如何学编程ith that (comments etc).

Also I plan to have 3) blog with preferably good comment abilities (open ids welcome again). I thought at first a blog engine might be enough but I think 1) and 2) could be not default option for blog engines.

Since I believe its a little bigger than blog, and way less then big CMS I belive there might be some intermediate answer here. I have looked at Orchard CMS for example, and it appears a little more advanced then my needs are.

DB is irrelevant, but id prefer postgreSQL, sql server, mysql in that order.

EDIT: I can see that mostly N2cms, Umbraco, Orchard and DotNetNuke are referenced everywhere. If someone could point me on a comparison those or compare at least some of them regarding simplicity and some other aspects it would be great. I also plan to use DISQUS for comments I think, but I believe its pretty easy to integrate with in any CMS or?

Question is becoming less and less concrete, but I believe most non specific CMS quesitons are and they arent usually closed here.

I would highly recommend Umbraco, which is a highly scalable CMS. You can configure Umbraco to run in any of the DB's you want. It's also relatively easy to learn if you get their Umbraco TV subscription which goes around $30/month. Umbraco also has a bunch of plugins that would help for comments(I would recommend UComment if you're looking for one).

Umbraco doesn't have WYSIWYG HTML generation out of the box but you could always use an external program to generate the HTML templates and import them into Umbraco.
