HackerNews has a pretty old user interface (fonts are too small and texts are all cramped together & don't look hmm polishied IMHO) but visit it daily due to the contents being awesome.
User experience is subpar due to slowness and other weirdness (links don't take you where you want & search results are irrelevant).
And also when a page loads, it prevents a user from clicking anything by showing a transparent layer which covers only 2/3rds of the screen.
Yes and Yes!!
