Leaving academia - what to do with the personal website? I have a question about "post-academia" personal websites. The question is open-ended and fuzzy because I am not 100% certain with what I would like to do, so I am also looking for suggestions.

Some background first.
I will soon finish my PhD and I will probably leave academia permanently for an industry job (and most likely it will not include any research). Despite leaving academia I am not abandoning my work and my academic credentials. In future (at least in the next 5-10 years) I would like to 


brand myself as a professional in the field with an emphasis on my academic contributions (I think that if someone googles my name and as the first result is listed my academic page that can only be positive for my image)
remain open to a potential collaboration with academia (e.g. projects that my company finds interesting; reviewing papers for conferences)
remain open to sporadically co-author papers that are related to my previous research (e.g. someone reads my paper, finds my work interesting enough to ask me to contribute to his future paper, but realises that I am not anymore in academia so gets a wrong impression that I am closed to such offers -> I would like to avoid that).


Now goes the question.

As many academics, I have a personal website with my research interests, projects, publications, and so on. I would like to retain that website, but I have no idea how to design it in the way it is sustainable and not dead for many years to come. I have seen that former researchers leave personal websites on the server of their former departments, but they look quite dead with an obsolete email as contact, old photograph, last update 10 years ago, etc.

But on the other hand, probably I will also not have any new content to fill since I will not be writing papers anymore, and my field is not like architecture where architects have websites with their portfolio even when they work for a large company.

How to design a "post-academic" website in the way it is sustainable? What content to put? Do you have any examples of successful webpages of former researchers?

Edit: I forgot to note that I have a Linkedin profile, but I don't find it as a good replacement for a personal website.

Edit 2: I'd like to make a website that is sustainable irregardless of the job and company I will work for (I expect this to change multiple times in the next 10 years).
Put your website on some other hosting than your university.
Write up-to-date status and contact, perhaps with a few words of explanation (e.g. to make it clear that is not only for archival purposes).
When it comes to rest of stuff, they can be the same. (Minding academic data and contact; when it comes to branding - it is a question for Workplace SE and answers will depend on your profession.)
