Set unique meta tags for blog posts

[francisli]

Right now, meta description is "A welcoming and inclusive volunteer group of activists who use creative technology to solve civic and social problems." for all blog posts.

Can we pull from the first sentence of the post?

Can we also pull the first image and set an og:image tag for sharing?
