Adobe has created a survey on their Security Matters blog with a survey for digital signature users to complete.

If you have (and use) an electronic signature credential, and are interested in helping Adobe craft the next generation of Adobe Acrobat, Reader, and LiveCycle products and signature features, we are offering you the ability to participate in an Electronic Signature Survey.

Might be worth filling out, if you want to have a chance to influence the next round of Adobe products, such as Acrobat.
