Flickr is now so in-your-face and slow loading, I can't stand being on the site. And this is from a guy who would spend an hour on the site looking for the perfect image. Not any more.
These services that are owned by big companies and are generally free (1 TB limit) don't have an incentive to make something for the user. They care about their customers the advertisers. You should rather invest in a service that's built by people who love photos and build the service with a clear business model. A model that powers the user. Where the user pays for the service and thus becomes the customer. Now any decision the company makes it has to put the users first who are the customers.
I am one such person who feels this way about these giant social networks. So I built http://pixter.in , a service that puts users first. Do check it out.
