Hope this is constructive feedback.
I'm relatively young, but i really like the old style of forum. The reason is, the worldwide trend towards low content density really grinds my gears. The esk8 forum for example, has about 3 words per page and information is utterly unfindable. To be fair, it's probably a good match for anyone who thinks it's clever to ride a3kW teatray on the sidewalk.
ES by contrast is so much easier for me. The text is a sensible (small) size, there's a lot of topics and posts per page, the colours are plain and easily differentiable.
Actually for me, the only substantial issue with it is the searchability and I'm not even sure that problem is soluble.
There are small things I might change, like eliminating the long obnoxious, space consuming signatures. Allow people 2 lines max.
Another thing I love is that we can edit pages months even years later. This is mainly used for the good, for example i vaguely try to categorise my threads on the first post and I like to update/edit factual information so that anyone who reads it doesn't have to trawl the next 20 posts to set if it was correct.
