I was about to embark on entering meta descriptions for these pages. However the thought crossed my mind, is it necessary for these pages?
Google seems to be quite good at picking relevant snippets out, and I wouldn't want to convolute the process of searching and discovering these pages with meta tags that will be sub par to the snippet Google would have otherwise served.
Is purposefully not entering a meta description on these pages a good idea? Or am I being an idiot? They just don't seem necessary for these pages, and also they would be difficult to write for.
