Imgur is exactly as much of a commodity as YouTube. The exception is that they host images instead, and when you consider that the images are silent webm videos a lot of the time, the lines are even more blurry. The value to both communities is just that, their communities.
Agreed; whilst there are some subcommunities that appear unscathed, YouTube comments are typically a cesspool of hurtful spew from the bottom feeders of human society.
> Imgur is exactly as much of a commodity as YouTube
Youtube isn't a commodity. It's the place that even your aunt, mother, grandmother, uncle will visit and knows to visit for entertainment or music. People who would never have a reason to visit imgur.
Commodity is when your product has no differentiation on the market. Imgur does not have enough differentiation on the market and that's why they're a commodity. For image centric community you can go to Reddit, Tumblr, or any kind of online forums really. Youtube's differentiation is that it has created significant network effect around public video hosting. Can you think of any meaningful competition other than Vimeo? (Or maybe a couple of others but they're nowhere as close as all the online forums online)
