> Datomic's is perfect for probably 90% of small-ish backoffice systems that never has to be web scale (i.e. most of what I do at work).

I don’t think I agree with this as stated. It is too squishy and subjective to say “perfect”.

More broadly, the above is not and should not be a cognitive “anchor point” for reasonable use cases for Datomic. Making that kind of claim requires a lot more analysis and persuasion.
