The first thing to note is that Reddit was not on the main list of the 50 Most Innovative. It was included in list of top 10 for Media, which is where we recognize innovators in a more general way within different industries. The main focus of Reddit's entry, after explaining the site to someone who might never have heard of it before, were the "Ask Me Anything" Q&As. Those interviews were far more social and newsworthy than most Q&As that appeared in msm. Although the series didn't start last year, it began gaining traction and became more newsworthy during 2011. Many innovations are slow to mature, or even fail despite their unique approach. The Reddit entry recognized that those Q&As have come into their own.
Here's a better example, and it does suck to single anyone out, especially one that I use and like:
Dropbox - the only thing they've done recently was take small evolutionary steps on the innovation they showed 5 years ago when they launched.
There was so little to say about what else they've done that you basically just mention they're growing and making money. Which is great, but does growth and revenue make them the 22nd most innovative company in the world?
Why are cloud and consumers criteria at all? That's why this list feels like such an odd mix - there shouldn't have to be anyone from the cloud, if they don't make the cut weighed against everything else in the entire world then do a separate list on innovation in the cloud where they can be recognized for their achievements without compromise.
Those aren't criteria, but the fact that they have designed so-called cloud storage in a useful way that is accessible to the masses is why they were included on the list. I also think that it is important that a cloud company be included in the list. So I wonder why you think there shouldn't have been anyone from the cloud?
I don't think the cloud specifically should be excluded or even a factor in and of itself, I think the most innovative companies in the world are by definition the ones who are innovating the most, cloud or otherwise.
Twitter belongs on the suspect list too, how can they still be one of the most innovative companies in the world for a product largely unchanged in 5 years, during which time a jaw bone was printed and transplanted into a person?
