And again about the tag cloud

The question has already been raised many times, but still.
Tag cloud on Habré and in many other places is a predominantly fashionable piece of reflection type in the logo, instead of performing a navigation function.
1. Often you can find such tags in a post:
SAL , studio of Artemy Lebedev , Artemy Lebedev , Tema , samiznaetekto , Lebedev

S.T.AL.K.E.R. , Stalker , Stalker , STALKER

web2.0 , web 2.0 , web 2.0 , web2.0 , webdvanol

')
etc.

What can I say, even how to write - “tag”, “tag” or “tag” - and that is not clear.
And in other posts there will be only 1 of them. The result is a tag blur, and it does not perform its function in the cloud. About typos and say no.
Solution: nevertheless to fasten autocomplete, bo habr and so does not suffer from a lack of javascript, and to make a class of "alias". Suppose that only the swan tag will be displayed, and all the others will be present in the auto-complete, but when you click on them, insert the parent. Edit alias to allow people with a certain karma, create - all.
2. Unnecessary duplication.
In any post on the blog about Google there is a Google tag. But not everyone will put the tag "web development" in the appropriate blog. Why extra movement and blurring? The tag with the name of the blog, if it is specified by the creator of the blog, should be automatically added to the post.
