at photographer/designer side things might look a bit depressed but
These stock agencies must have an idea what they are doing adding 200k new images a week...
totally agree on that. well plus things change fast;
5 years ago there wasnt a work defination which takes place on networking web sites. recent days brands spending affordable money on these sites and their agencies / PR departments are publishing daily posts and using images, videos to capture followers attention fast. its happening on web and not only on twitter facebook or foursquare, its more and more becoming like famous movie "minority report" kinda thing; news that you might read, ads you might click, updates you want to follow...
at this speed no one can use huge productions for daily, even hourly updates that you post for instance on your brand's facebook page
neither you can use same "goooood morning dear customers!" message with some image over and over again...
i think stock agencies are trying to fill this gap with keeping things fresh. While doing that; the sense of circulation makes designers and photographers feel a bit depressed to follow up and create more and more in same time.
the next big thing is Asian stockers flooding the market and you can't compete with their cheap production costs in Vietnam/Indonesia/Philippines.
Well i don't think thats the case either. An Indonesian won't take your portrait/local/regional/tradinational/daily photo. All effect that may cause is seeing more blackboards and hand gestures againist some invisible screen and that kind weird things. In short mostly low productions and great cliches...
So I see no reason to be afraid of taking steps.
