Buttons are not working for me.
My browser is Google Chrome Version 37.0.2062.20 dev-m
I see 3 errors in the Javascript console: GET http://www.google-analytics.com/analytics.js net::ERR_BLOCKED_BY_CLIENT (index):507 GET http://cdn.mxpnl.com/libs/mixpanel-2.2.min.js net::ERR_BLOCKED_BY_CLIENT (index):546 GET http://static.olark.com/jsclient/loader0.js 403 (Forbidden) (index):1
I do allow same-party interaction and cookies. (i.e., anything from montagebook will work.)
You may want to set your third-party analytics services to be asynchronous, so they aren't a single point of failure for your entire application.
