Adobes acquisition of TypeKit wasn't terrible; it's pretty much been the same since its inception.
Other acquisitions have been more questionable (time to shed a tear Fireworks and Freehand users) as IP have been consumed and products have been left to rot.
In the case of Flickr, Adobe would probably keep it as is.
Other potentials could either consume or really push a tie in with existing services.
In summary, best suggestion from a bad lot
Yeah I agree with this. Worst thing that can happen is they integrate it heavily with their other products but since a lot of people already use both it wouldn't be a bad thing.
Though I don't want Flickr to die (its a very good community, and i love it) Adobe is not my first pick to acquire it. If anyone should buy Flickr it should be a company that does things quickly and innovates. Adobe is notorious for bloated software and apps (just try to find something specific on their website without google, its impossible).
With Apples new initiatives to showcase people using their products, I would be interested to see them behind the wheel of flickr. But I doubt that would happen.
Zuckerberg is the more likely candidate, but I doubt he would buy it as well.
Either way, Adobe is my last choice.
What about 500px? They are in the same business and in some ways they have the same functionality and experience that Flickr used to have. I doubt they have the money thought so it's mostly a thought experiment.
I agree that they run the same business basically, but 500px is almost entirely pay-to-use, because of severe limitations with the free accounts. So they would acquire Flickr, and then it would disappear... basically buy it to remove competition.
