I have a couple of suggestions for the blogs.
1) Put titles in CDATA or encode characters so they display correctly on RSS. For example, an ampersand is showing up as & amp ;
2) Add a way for us to add Open Graph metadata to make sharing on FB enhanced. Right now, links to our blogs only show the blog post's title; but the description and the image are the OG metadata from our community's theme (OG metadata added to our custom theme header). This is a description and image for our general "community"; but doesn't necessarily pertain to a single blog post. If there is a way to update this for the blogs, that would be great. For example, if the blogs could have a different theme applied to them, then on that theme, I wouldn't use the general community OG metadata in the header; I'd leave it blank.
3) Allow Collections to have SEO-friendly URLs as well. Right now they are "unfriendly" URLs full of numbers.
