Hey Daniel,
To be honest with you, the only reason that we don't load any WYSIWYG editor for the event description is to avoid 2 issues:
1. People tend to "decorate" descriptions which makes the event listing look extremely ugly and not unified.
2. Bad users that tend to inject html codes and mess up your layout.
Anyway, the good news is, I will see if we can add this into 1.4. The reason that I am thinking of adding this is not because of your harsh remarks (don't want you to get the wrong idea) but your comment is pretty constructive and I see where you are coming from as an end user
Now back to the issue with the social sharing, this seem to be working for me now, not really sure what happened. Did you tweak anything? Upon clicking on the social share link, this is what is appearing for me,
