Look, I'm just another noob but......
If you collect personal information from your visitors, than a privacy policy may be something you would want to post.
If you provide a service, that a "terms of service" may be something you may want to post.
If you don't collect personal information or provide a service to your visitors, than neither would be necessary.
With that being said, In the 10 years I'm been making "terms of service" and "privacy policy" pages, I don't think a single visitor stayed on one of the pages long enough to read past the second paragraph. Probably the only visitors were there to scan the text to copy/paste to their website.
I believe the fact that you have a terms of service and privacy puts people at ease, regardless of what is included in it.
Then again, I'm just another noob.
