> a frontend to SharePoint

No wonder they just tossed Skype in the trash. This explains so much.

> SPOL is even worse a tirefire than, say, even Lotus Notes.

To be fair, Lotus Notes is what we had back in the mid 90's. There really wasn't much else like it. But comparing that today... (checks notes) ...oh. It's still a thing?!

So, neither Lotus Notes (now "HCL Notes" apparently?) or SharePoint have any excuse being as bad as they are. There are a dozen other far more capable examples of this kind of technology. I'm routinely amazed at how bad MS' user experience continues to be, even with all the money and engineers at their disposal.
