Café mentions are now improved!

You can now mention a cafe using ! now instead of #. This is so that we now have hashtags free for search use. This also helps with importing and sharing across platforms. We will be making a lot of changes in the next few months around being more friendly working with other networks while keeping our same ideals. As users move between multiple networks we want to help users migrate easily without needing to learn the differences in conversation/post formatting.
