Tags work as clickable filters to sort the content of news

[Sergyenko]

Let's make tags work in the way it works on the other blog / news sites

[Souravgoswami]

The current implementation goes over all the articles and generates a page with the tags. I have added id to each header, so we can refer to a tag with /tags#ruby (ids are downcased). It makes the tags on home page clickable, where each tag is link to /tags#{{ article.tag }}

I think we can sort the tags by date of the most recent article, otherwise AND stays on top, for example.

Caveat
This can't be done like rails, where I can use &tags=ruby for example, and it does a database query. Jekyll has to generate a page full of tags. Thousands of tags will make the page very big. Currently pagination is done on the /archives/ so there's no way to add pagination/infinite scroll on tags. We can limit the numbers of items on each tags, based on dates, but we can't do anything dynamic here :(

What do you think?
