I don't know... I like regular IOTD. Isn't there some way of fixing it up or promoting it more?
The twitter thing is fine but I personally don't do twitter, don't have any desire to start, and the people posting in the #screenshotsaturday feed are not www,gamedev.net users so what's the point of aggregating their content here? Also don't know a lot about twitter but isn't the popularity of various hash tags extremely fickle? What if screenshot saturdays is a fad that everybody forgets about in a month or that only the same few people keep up with week after week?
The problem though is that the submission rate isn't there with our IOTD.. It's hard to compare 200+ screenshots per week of games in development versus the 1-2 we get per week. And the submissions we do get include a lot of commercial middleware rather than just regular joes making games. Clearly something isn't working. Using twitter though creates a strong feedback loop and that's something we need. What I added yesterday was the ability to add our own comments as a community to screenshots.. which is good.
I think we're in an age where game developers and twitter go pretty hand in hand. The game development community is *incredibly* active on twitter.
But in this case, #screenshotsaturday has been around for years and years and is actually growing in popularity. What I think I might do for users who don't have twitter is to post a link to their screenshots on our own twitter account and reference #screenshotsaturday. I'm still thinking about this.
