Thanks Awn 
I do have a list of quite a few of the key posts but to be honest, I’m not doing anything special here 
All I’ve done is figure out how to get search working in this community for example, @hugo profile (as Hugo created the post), was what I used to find that post & I often use site:monzo.com/blog + keyword(s) to find Monzo’s overviews of a feature. If you’re looking for a comment from someone from the Monzo team but you’re not sure who’s post was most recent / relevant, you can use group:monzo + keyword(s).
Then as long as you can remember which keywords to look for & ideally, who’s post to check, it’s usually pretty quick & easy to find anything
