Oops, I meant to reply, not upvote.

Sharepoint is only really utilised because it comes as part of Microsoft's enterprise package. More often than not it is recommended/purchased by the IT department solely, without any other input from management. Large companies can expect massive seat-based licensing costs in the millions, year long implementation timelines and poor uptake rates. I will probably get downvoted but I speak the truth. People should be fired for their choice.
