What do you think about adding thumbnails to the blog?

I was thinking we could categorize every post using the tags, and for every tag we would have a generic pic to add. So, one pic for logs, one for core posts, other for urgent stuff, etc

these general thumbnails would appear only if there is no post-specific pic. If there is a post-speicific pic, that one will appear instead.

I'm thinking for example at the Chameleon and butterfly release. For those we had cool pics and they could be shown in the general view and the post-specific view

the screenshot is only a quick mock up with no css, so take it for what it is. I also added a date for each post.

let me know what you think about it, so in case i can implement it and PR it soon.
