Like everything in life, there are always exceptions. I generally won't sign NDAs either but I gave the green light to signing one today in a case where our potential client is abandoning their dev team due to failed promises, technical issues, and a timeline that has kept getting longer and longer. This client wants me to review the application as it stands now to determine its quality and figure out what needs to be done to fix it. In this case I was okay with signing an NDA that was solely restricted to the data residing in their existing database, and I added in a clause that specifically excluded source code, design, technological processes, etc., from the NDA. To me, it's not unreasonable for someone to ask for an NDA to prevent the disclosure of data such as contact lists, email addresses, login names, and other private details. I won't sign NDAs that cover ideas or anything technological, but these kinds of NDAs are just due diligence on the part of clients, in my opinion.
