> the uglyness makes sites hard to navigate and hard to use

No, ease-of-use and beauty are different things, though often conflated in rants.

I've never used any of those sites so I cannot speak to that aspect, but as far as beauty is concerned in a lot of the examples the ruby site looks more trendy, possibly because they are newer, because python has been around for a bit longer?

Site-wide redesigns are rare for content-focused technical sites, especially volunteer-based open-source projects.
