@cypnk this is admittedly a cynical British view but I think a lot of colleges no longer encourage "giving away" educational material if they cannot monetise it by marketing paid for courses; and a lot of uni stuff disappears behind "student portals" you need ID for...

With regard to hobby sites disappearing, alas, I suspect many were edited by people in middle age who may be in good health today. At least there has been an effort to prevent the knowledge being lost.

@vfrmedia That may be the accurate view though. Education is a business, first and foremost. Your degree is a product sold over time and which society has collectively decided is worth something (or has been indoctrinated into believe so)

It's true about hobby sites as well. The "digital will" is a fairly new concept. I've made arrangements now to have my intellectual property from my writings, to programs, to photos (It's a hobby) be released to the public domain

@cypnk through my day job (sysadmin for 2 seniors homes) I see at first hand the effects of age, especially on folk with "intellectual/tech" careers.

Although thankfully not everyone gets dementia and having hobbies can keep some of its effects at bay; mobility/dexterity limitations are still an issue.

At least it is now more feasible for a patient with an active mind but limited mobility to bring in their computer and still edit their digital content if they wish..
