Is it a good decision to include monospace fonts in UI?

I'm working on a blogging platform which have a community of writers.

My dilemma is that a pairing of serif and sans-serif will probably stand out much better, thoroughly legible and reader friendly (sans-serif fonts work best because they are the ultimate solution for digital reading), but should we completely disregard the affinity of writers towards the monospace fonts?
