Cant wait to test the wallet! i use samourai wallet at the moment.
Maybe create a site for txt3 where you can post to multiple sites at once (facebook, twitter, pintrest?), i used to use a site like this a long time ago but it became commercial and then changed names, i think it was called ping.
Another idea would be to host a browser addon on txt3 that would allow you to text on any website from a side panel. Again i used to use a service like this many years ago called daisy, but it shutdown after a few years. It made the web alot more fun, i loved it, there is nothing out there like it. https://web.archive.org/web/20080212195959/http://www.dai.sy/
