To me, CrazyGuy has the numbers to make it the go-to place. Not as polished as some sites. The webmaster can be kind of a polarizing figure. And, as has been said, you don't have full control like you'd have on your own site. But it has a lot of users, and to me, that makes it very useful. Some people have questioned why you want to bother sharing your journal to begin with. For me, it's fun to read, it's fun to write, and it's informative. If I want to ride through an area, I often want to have some idea of what to expect. A Google search
might bring up one or two personally-hosted journals, but CrazyGuy lets you drill down to anyone who has tagged a specific area, county, city, etc. When I started planning a trip to ride the GAP and C & O, it was pretty easy to pull up CrazyGuy journals of people who had done it. Somewhere recently in this forum you can find discussions of biking from Ohio to Pittsburgh: the potential trails, the river crossing in Stuebenville. Part of researching this route for me involved pulling up every journal that mentioned Stuebenville, so I was able to see what to expect in terms of hills and dealing with a river-crossing without a really bike-friendly route. Stuff like that makes
https://www.crazyguyonabike.com a useful site, and often an entertaining one.
