I feel the What topics can I ask about here? page needs a minor edit. At present, this page still contains a link to the no-longer active blog (see screenshot below):
While linking to the blog itself is not necessarily a problem, I do feel it is a problem within this context. The reason being that the whole purpose of this paragraph is to help users understand the Q&A setting of Ask Different is best suited to questions about practical problems, rather than to discussion type questions. It then refers users to the chat room and blog if they have an opinion-based post (at least that's how I'm interpreting it).
I propose we remove the link so that this sentence now reads:
We do have a chat room for opinion-based posts.
Or, something similar to the above.
