This is not the first product of the kind and won't be the last one. And they look great in theory but get complicated and very confusing and ultimately never find their place. People don't need an integrated tool that does everything. People need a few very good tools that work well with each other. Confluence/Jira is such an example, and to some extent Google's suite and Microsoft's, plus a few more. Unless you can…
The integration story didn't work that well back then, and that was when any one of those "integrated suites" cost the same up front as any single office tool, so the cost savings was more significant.
I still like the idea, but it seems harder to make it work well now than it was in the 90s.
