Our benevolent forum overlord, aka Esquared, informed me some of you had some issues with our updated 
Terms of Use and 
Privacy Policy. I thought it best to chime in and assuage your fears or confusion over the newest legalese. In particular, I understand that you are concerned with the following clause:
Our License to User Content. When you post User Content on or through the Services, you grant Purch a world-wide, perpetual, irrevocable, royalty-free, non-exclusive, and sub-licenseable license to use, copy, distribute, reproduce, modify, edit, adapt, publicly perform, publicly display, translate, create derivative works from, sell, lease, transmit, disassemble, and publish such User Content, in whole or in part, in any format or medium now known or developed in the future, including without limitation for promoting and redistributing part or all of the Services (and derivative works thereof) in any media formats and through any media channels. You acknowledge and agree that your user name may be associated with any User Content that you post.
This language is not that different from language used in the previous Terms of Use:
6.1 By sharing, submitting and uploading any User Content, you grant Purch a worldwide, perpetual, irrevocable, non-exclusive, royalty-free, sublicensable and transferable license to use, copy, distribute, display, publish, perform, sell, lease, transmit, adapt, translate, modify, reverse-engineer, disassemble and create derivative works from your User Content in any legal manner for the benefit of Purch. 6.2 You irrevocably waive and agree not to assert any rights that you have to prevent us from exploiting the rights granted in Subsection 6.1.  6.3 You also grant us the right to use and display the name that you submit with any User Content in connection with such User Content.
I also want to point out that this clause is standard across most communities and publishing sites. For example, here it is nearly word for word in 
Reddit's User Agreement:
By submitting user content to reddit, you grant us a royalty-free, perpetual, irrevocable, non-exclusive, unrestricted, worldwide license to reproduce, prepare derivative works, distribute copies, perform, or publicly display your user content in any medium and for any purpose, including commercial purposes, and to authorize others to do so.
While the exact wording may be jarring, the clause enables us to 
publish the forum on a worldwide basis, and 
on different platforms as they evolve. It allows 
access to the forum via different kinds of devices and ensures that 
we do not have to unexpectedly pull down forum comments and threads. In order to publish the forums worldwide, and allow you to upload images, text, or any other contribution to the forums we must have "world-wide, perpetual, irrevocable, royalty-free, non-exclusive, and sub-licenseable license….". Without that clause we would have to constantly re-evaluate our ability to offer the forums to people in different locations and who may want to access it through different channels or devices.
The AnanadTech Forum is a free service provided to you.
 We require that the grant of this service to be “royalty-free” as we wouldn’t expect that you would charge a royalty for the content and images that you post on AT Forum, or that you would post third party content requiring royalty fees. All of that said, please note that 
the grant of rights is non-exclusive and you retain ownership to it even after you post it.
