Here's the interesting part (or at least we think so).
At the same time that we are developing OMTTS.com, we are also developing OMTTR.com where the "R" stands for "rock" as in OneMillionThingsThatRock which is the direct counterpart to OMTTS and is where users post text or text and photos of things they think are great and people respond.
At some point we may develop websites using other letters of the alphabet for the last letter. Which means that the emphasis and the branding needs to be on the OMTT part of the name so that the websites have some consistency yet users know they are different based on what is done with the fifth letter. So when you submit your designs we would like to see designs for both OMTTS and OMTTR.
We also own the full URLs for OneMillionThingsThatSuck.com and OneMillionThingsThatRock.com so it's possible those spelled out names could be incorporated into the OMTTS and OMTTR logos if you think that looks good, although what should be dominant are the big all-caps OMTTS and OMTTR.
As for the look and feel and design of the logo(s) we are wide open. The challenge is to design them so that each website can stand on its own but at the same time users know they are part of a similar family of websites. One idea might be for the roll-over "Hit Counter" to be part of the actual OMTTS and OMTTR logos, or part of the website headers ...
