When I link to one of my WP posts in my Twitter TL, half the post and pic get automatically embedded in the tweet. Like here: https://twitter.com/_traxor_/status/316185241045843969
I don't want that. How can I disable that embedding? I'm not even using Publicize, just manually adding the post's URL to my TL, and still it happens.
The blog I need help with is tr4xor.wordpress.com.
