Like any good twat, I was going to correct someone on the Internet and decided to search it up again.
According to this top result (I didn't look any further), basically you can use whichever you want, just remembering that of course if you use "of" then you need "a" in front. It's either "a myriad of x" or "myriad x" but they are basically interchangeable. Yes, one's technically a noun and one's an adjective but as far as I can see that's an uninteresting difference considering in both usages the word will always mean the same thing.
It's good to remember that it comes from an actual countable number (originally 10,000), but that also isn't particular useful as you'd happily say "there are a hundred issues" but you'd never say "there are hundred issues" or "there are a hundred of issues" so it's not like you imagine it as a number in your sentence construction.
Here are the 45 uses of the word on the forum: search.php?keywords=myriad (including declarations of course). Highlights include:
- Phil stating that it's never correct to use the singular version with an "of"
- Corby going from never having heard it used without "a / of" in 2009 to using it without himself in 2013
- Scrolling down to asking the question yourself 13 years ago and realising the whole post you're writing is basically pointless but you've got this far so you're going to submit it anyway. (* damn, time flies)
- I felt confused by the myriad of incestuous familial linkages.

Do you have an opinion? Which do you usually go for? Do you panic every time you write it?
