Another feature of SquareSpace 7 is that it has 'Like' and 'Share' buttons. So now if you have no time to think of a comment or you just don't like leaving comments, then you can just click on the Like heart at the bottom right of the post to give me some indication you liked a post.
The 'Share' button allows you to share a post to Facebook or Twitter, although I am not too sure that this is working properly because when I tried to Share to Facebook as a test it did not work. But I don't know if this is just because SquareSpace does not let you share you own posts or whether something else is wrong.
So please 'Like' away with gay abandon, and fell free to do the occasional 'Share' to Facebook as well. It might get me some more readers.
