Thanks! Made it work for sharing individual blog posts! (added {permalink} in the html code)
And agree with many others on this thread that share buttons should be a standard feature, i'm new to squarespace but quite disappointed on this.

After trying other services suggested in this thread, which were less than ideal for various reasons, I discovered this.  Free and simple.  No javascript needed.  No tracking by a 3rd party (that I can tell. . . at least there were no "terms of service" to agree to).  Works great!
