blogcatalog is a blog social network and directory, it really reminds me of MyBlogLog.

Features

Browse folders, tags, country, user, language or search…here is a directory entry, and here is a tag entry (both of these have RSS feed updates).
Something else I noticed is that you can search within blog post tags, ie. find posts tagged with a tag, is this an attempt at Technorati Tags?

Here is a random user, sections are:

Neighbourhood - blogs you follow
Friends - users you follow
Recommneded neighbour’s - this must be users similar to you based on your friends and who you follow
Recent Viewers - with widget and all, just like MyBlogLog
Shoutbox - messages

Here is an example of a blog space, sections are:
Details - info/specs
Latest posts
Comments
Neighbourhood - users that follow your blog
Related blogs
Blog stats
Rate blog

blogcatalog also has a discussion forum, and you can even save your favourite items.

All that I see missing is real-time chat and uploading your OPML Reading List, to encroach into the SYO area.

Ziki is similar, but different, you can re-syndicate all your stuff in a Lifestream, upload your OPML Reading List, blog posts, tag yourself, message people…one is a blog social network, and the other a people social network (both discoverable by tags).

mashable also notes that Technorati could become a blog social network, at the moment for each blog it lists users that have “favourited” that blog (almost like adding a friend…only displayed as a Public RSS Reader), next it could list site visits, just like MyBlogLog and blogcatalog.
I also mentioned how Technorati could absorb the service AutoRoll as a feature.

I really like the idea of blog communities:

MyBlogLog/blogcatalog - fans of your blog, site readers, recommended blogs/people
SYO - Social OPML Reading List…find people that have similar Reading Lists, see people who subscribe to your blog
AutoRoll - people who visit your blog also visit these blogs
Feedburner - records the number of subscribers to your blog

My only gripe, like I mentioned in Personal Network Clouds post is it is a real effort to join a blog community and start adding blogs as friends, haven’t I already done this with my blogroll or RSS Reader subscription list…can’t I just plug in this OPML into a service, just like SYO.
