Generally speaking, I’d recommend not looking for a hiking partner. The reason is that everyone has different objectives, goals. Also, everyone has their own routine for getting up and going in the morning, and their own hiking pace. In other words, hike your own hike.
This is not to say that you should expect solitude. You will meet plenty of other people at shelters, in towns, and elsewhere along the way. You will be hiking with an everchanging pod of people. It changes when people go into different towns and spend different amounts of time in various towns along the way. Some go in and get out. Some take a zero. Some bypass towns.
If you are fortunate to find someone along the way who is going your way, who shares your goals and objectives, and enjoys your company, then go for it. Enjoy the companionship. He will probably become a life long friend (Right Pace-O?)
