Idea: Browser extension that reminds you to tweet something
Platforms like YouTube or WordPress can automatically post something on Twitter for you. For example when you liked a video or posted a new article on your blog.
I like that feature because most of the time would like to share that stuff on Twitter. But often I would not. I had that feature enabled on YouTube for a few days and it spammed my hole timeline.
What I think would be cool were a browser extension that recognizes when I give a YouTube video a "thumbs up" and asks me if I want to share that on Twitter.
And not just on YouTube but on many sites where it makes sense to integrate that. Maybe when you comment an article of your favorite blog.
