I personally care about them, I saw about a 30% increase in conversion rate once added (vs a standard Let's Encrypt DV cert). The cert paid for itself in literally less than a couple days.
I've personally never (knowingly) seen the EV extended green bar generate any positive change in general end user buying behaviour.
I'll be willing to bet that few of them will be able to usefully debate the merits of EV over DV though 8)
However, it is a start and I'm glad it works for you. It would seem that the message is getting through a bit. I own an IT company with 20 odd employees and I estimate that roughly 50% of those staff would be unable to tell me exactly what an EV cert is for as opposed to a DV but to be fair they are all rather good at looking for the signs that a site is dodgy (or bone fide)
Why ask something as esoteric as the differences between EV and DV certs to end users, instead of the differences (albeit cosmetic) they actually see.
