you see a welcome wizard when you open it.
it has pages, as the arrow show clearly (maybe this is not understood?)... and the 3rd page is literally a pointer to resources to learn pharo (including a small tutorial called ProfStef and an online MOOC).
and of course, joining our discord server (invite at: http://pharo.org/community) is the best way to get help and guidance in fast way, we have several channel dedicated to help newbies :)
Is a generic purpose language, and there are generic usages, and a lot of examples :)
But here you have a huge SaaS made with Pharo: https://yesplan.be/en, and here you have a small mobile app made also with Pharo: https://plc3000.com
[edit] technically is not a mobile app, but runs in any browser so... yes :P
there was a problem with the PhL, that took more time to update of what we thought. Now it should be working... but please take into account that 32bit versions are deprecated (unless you're working on ARM)
it doesn't yet support the whole IDE (because it has some other complications, we will solve in next release), but it supports application development with it.
weird, it loads correctly for me.
Yes, a bunch of companies (some of them very important in their fields) are backing Pharo... but Pharo is a community effort, made by hundreds of people.
