The way you laid out the beats of your original comment made it sound sarcastic if you read it expecting the usual off-hand snark that's prevalent on the internet, so "makes perfect sense" would turn into "makes no sense at all" - therefore seeming like the product is useless or a step back when web pages already exist.
Thank you. Your feedback is helpful: In hindsight, I can now see my comment could be misinterpreted as sarcastic, even if that wasn't my intention. (If anything, I think giving people more/better tools for creating online content is great -- with the obvious caveat that all this content will reside in "private webs of documents" controlled by a single company.)
It seems we've all come across so much (unhelpful) sarcasm on the web that whenever we see certain phrases or grammatical constructs, we are unconsciously preconditioned to think the intent is negative -- even when it isn't.
On my end, I'll try to be more mindful about my phrasing next time.
I understood it as intended, but I can see how people would read it that way. It has roughly the structure of a "it's just x with y baggage" comment at the outset and could trip that wire in the mind of someone who doesn't finish reading before commenting.
edit: more comments appeared while I was drafting. I guess it never hurts to have the same feedback framed different ways...
