On my site, http://whatgoeswiththis.co, I'm getting persistent errors found by Google Webmaster Tools for my markup of UserComments - it's saying that at each instance I'm missing location, name, and startDate (2 times) properties.
I didn't see anywhere that these are required, and I don't have geolocation of any users' comments on my site. Is this simply an error I can ignore, or might it be better to simply remove the UserComments markup from my site?
Update: it appears from this page that because UserComments is a subcategory of the event property, google seems to require these three fields: https://support.google.com/webmasters/answer/164506?hl=en&ref_topic=1088474
Perhaps the answer is to use 'comments' property instead? Or just leave as it is? Thanks!
