I like that it's easy for people with no programming experience or even just basic computer skills can figure out how things work pretty quickly (and there are lots tutorials).
It also has some nice features such software development kits which help you learn more about coding without having too much technical background required before starting your own projects within protêge itself! The fact we have been using this tool since 2008 makes me think they might be doing something wrong when updating their products - but maybe i'm being paranoid? Also not sure if any other programs could give us similar functionality at lower cost price than what Protegete offers nowdays.. We're solving problems related business processes management so far everything works fine except customizations/extensions made outside official tools would require learning new languages etc., otherwise great product overall very stable platform used daily across several different departments.
