No problem with markdown.
As for the follow-up links I checked again and these are normal links. I'm somewhat surprised that they are used that consistently.
Can you also provide a tip on tags?
I didn't answer about tags because I don't know of a guide.
I just found that if you search on tag [word that you think might be a good tag], you'll get lw articles with that tag, but that would be a process of exploration rather than knowing about common tags.
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous thread is at close to 500 comments.
