A good question indeed about Cognos demand in Europe. Until a few years ago, I lived and worked in the UK, and at that time there was still strong demand. I'm now US-based, and still spending most of my time on Cognos.
I think the drop in site traffic is really down to two things - fewer people using the product, and also the fact IBM now has its own Community which overlaps with this one.

Yes, Power BI etc. have taken quite a bit of market share. I saw the IBM site yesterday which does have more questions but this site is much more organized (folders for diff tools etc.).
Maybe someone should start a site where resources can post their resumes and organizations can post their requirements for hiring employees as well as requirements for consulting projects.
Currently, the companies have very few choices when they have a project and they have to give it to their existing consulting company who expands the project to charge more time. They just don't know which other consulting companies exist.
