We've some a long way since the instamatic camera and notebooks....or maybe we haven't. Anyway there are now multiple ways to keep people up to date with your tour. Of course there's CGOAB and you can have your own blog on WordPress, Blogger and Tumblr. But the simplicity of posting pictures with comments to Instagram, Twitter and Facebook is also attractive. For my next tour I think I'll use Instagram and cross post to Twitter, Facebook and my blog. What are you thinking of doing? or what have you done and how did it work?
