After trying out the user chat feature with my girlfriend yesterday, she brought up a really good point. I did not tell her that I was going to initiate the chat request with her, however when the chat notification came up, she promptly ignored it and closed it.
When I asked her why she did that, and let her know it was me, she pointed out that it looked like a popup / spam. Especially since its a generic message saying something like "The Webmaster wants to chat with you." In this day and age, people are certainly going to react as my girlfriend did and ignore that notification.
My suggestion would to make this message more personal to the specific site. Something simple like changing the "Webmaster" portion to the actual site's name. Or even better, pulling the image used for the notification from the server allowing users to create a custom graphic.
Just a suggestion.
