You are making it worse.
Why are some titles very light grey and illegible now?
Why is the text a bit too small now?
...are you rolling out features piecemeal becasue now there is the most pointless of internet fads; the jump to top link. All over the place.
This is never ever ever used by anyone ever you know.
Why don't you make the site work properly in mobile before doing all these bizarre and detrimental alterations?
