yes some have capitilized putting them online

maybe you can monetize them and help fund your events
or do you already and I missed that

lot of conferences routinely record the talks and then post them

at more informal conferences the anecdotal information gleaned from
the talks can be real good

not always possible to go the conferences for a lot of people due
to time, money, etc..
