Everyone loves showing Digg / Tweet / Like badges on their sites, and the Disqus Comment System begins to give up.

The advantages of these systems from the point of view of developers:
- You do not need to program the complex, fully functional logic that these seemingly simple systems require.
- You do not need to handle database scaling problems or application performance problems that may arise if you created a comment / like / digg look-a-like and it became popular
- All collected data becomes part of the global data set.
I wonder if you know of any services that perform the following (each number on the list represents a hypothetical other service):
- Lets you tag add an element to your page. Perhaps a javascript api that allows users to click "tag this" and they can add 1-5 tags for your blog post, and the service saves your blog post by identifier (url, database id, etc.) AND to tags. Will work exactly the same as Disqus, but for tags.
- Let me vote or rate the item on your page. Like the StackOverflow voting system, a service with a javascript api that created a widget to associate a piece of content by id with voices.
I mean, haven't these things been invented yet? Or were they tried and failed? If the comment problem has been resolved, it seems crazy that tagging and voting have not been resolved equally.
Is anyone working on this, or is there something already there? Or do you have a workaround to create current systems there like this?
Waiting for your ideas.
Note. I am well acquainted with all libraries (I am a ruby guy, so all actions are like gems, etc.) in order to implement these things myself. I ask this question to try to find a fully functional system that is as easy to use and scalable as the services listed above, requiring only a javascript file. I tried the internet for them with no luck, but again, new services appear every day .
