Sync items to Facebook or Twitter

[YokoDesigns 10]

Anyone know of a way to sync a new item for sale to social media sites? For example, if I post a blog post, I can set it up to immediately show up on Twitter and Facebook. It would be awesome if every time I listed a new item, it could be redirected to a FB or Twitter page. That way I don't have to go and add it there every single time. Listing items is a lot more work than I expected

Thanks,
