This reads as so pollyannish as to be nonsense.

I'm not a fan of pollyannish declarations, but I try not to dismiss ideas on delusionally enthusiastic tone alone.

I've been around long enough to know that sustained collective enthusiasm can sometimes blindside you.

I took a brief look at the posted projects and quickly surveyed the community behind it and I'm not ready to dismiss them yet. I'm not exactly sold either, but I am going to put them on my radar and check in every few months.
