I definitely see the merit in having two or three, since this is a major landing spot of reddit refugees who would benefit from an introduction such as both the 2nd and 3rd posts, but the 4th is not really helpful despite being funny, apart from those chat links which should be in the sidebar rather than a random post, and the 5th is literally empty, even if polite.
It looks dorky. Apart from the General Discussion sticky, all the rest could be merged into a single new post. It’s not that big of a deal though.
