Just installed it tonight on Linux, no blockchain to download and was up and running in less than 10 minutes. A huge plus in my book. Low barrier to entry if you already have bitcoins to buy ARK with. The only downside is just googling "ARK" will bring up posts about the video game lol.
Initial impressions are positive on the front-end, but I'm still investigating the tech.
This is my biggest issue with this coin, I really think they should consider renaming it before it gets big. Most people going to associate the name with Ark: Survival Evolved. That game is insanely popular and will not be beaten in SEO anytime soon.
When Ark the token on page one and eventually will be on #1 or #2 spot then more Ark gamers will buy the token. This is a win-win.
