I liked a post on twitter. Then it came up in my feed again without my like. So I liked it again, clicked the post to get a page with just the post, and shift-reloaded that page. The like count dropped from 30 to 26, again my like being lost. BTW, the post has been up for 9 hours had has more than 5000 views (although that might also be manipulated downwards).

Twitter is still not worthy of trust.
