Pretty self-explanatory. It would just have you post a link to the project there, however by default it would be set to /r/scratch because that's where it would probably be posted.

However, while Facebook and Twitter do have some inappropriate stuff, it's not all over the place. However, on Reddit, there is inappropriate stuff all over the website, so I don't think the ST should show that they support the site by adding sharing functionality.

My advice: stay away from reddit.

I challenge all of you to find one NSFW post on the scratch subreddit. Just one.

I did not say “In the Scratch subreddit”. I said “all over the website”. My brother was on it, and day after day he told me about something inappropriate he found or posted that day.
There is inappropriate stuff all over reddit, even if not in the Scratch subreddit. Because of that, I don't think the Scratch Team should show any support for that site.
