That's yet another name added to the list of sites and business accepting cryptocurrency as a payment method. I've never used Craigslist and I'm pretty positive, at this point in time that I never will. But it's great for people who do I guess. Nothing too major for the ecosystem nor for the price.
Not that much of a big deal. It's not 2013/2014 anymore where entire articles were dedicated purely to a single merchant accepting Bitcoin.
You're probably right. I wasn't here in 2013-14 but I can imagine that it must have been a big development if a merchant started accepting bitcoin. Right now I think I will only be impressed if Amazon starts accepting bitcoin or another crypto.
