I don't know what people intend when they say 'like linux', usually I think it is intended to be derogatory.
We have seen snippets of what I mean. SecureAE.com was built so people could invest in Nxt AE with bitcoin (the conversion to Nxt was hidden). It was useful to bitcoiners.
Jl777 has asset to asset trading (some assets backed by crypto like BTC) in Instantdex/Multigateway. It's actually asset > nxt > asset trade but automated so seems like one trade. People wanted this and find it useful.
Sebastian256 proposed an idea to use the new Voting feature to allow centralised businesses/clubs/societies to use a regular username/password website to record completely decentralized voting results. It could even have a plug in to pay to fees in $ and convert to Nxt automatically so Nxt really does become like TCP/IP, invisible.
It takes time to do but the tools to do it need to be there first.
Coming from me, no... When I say "like Linux", I mean it's open source, more for devs to be tinkered and played with to create something. Ordinary people may not appreciate Linux, but they don't know they use it all the time. A lot of webservers are run by Linux/Apache for example.
Edit: Do you use Linux?
