A very interesting question. My guess is that you will find as many reasons as there are people doing blogs/web pages.
I think we started doing our WEB page a long time ago. It sort of grew out of our editing a Newsletter for people who had boats like ours. Everyone was desperate for more information on doing projects and wanting to know what others were doing with their boats.
From there, once we set out, it was to keep friends and family informed of what we were doing and where. I also have to admit that a small part was to show some of the people I used to work with that you can retire before you hit 65+!
Before we started cruising our selfs, we LOVED to get and watch videos on cruises that others had done. Like “600 Days to Cocos Island” and “Blue Water
Odyssey”. As it got closer to the time for us to go, we were finding that cruising videos were getting harder to find. No new ones were being created. We also could not find ANY on the Sea of Cortez
. So, we decided (after we had been out for a year) that we would do one as sort of a “payback” for all of the ones we had seen. Also, sending a short video to family and friends was a lot easier than trying to send back hours of raw video.
AND, when we are old in a rocking chair, we can look back on our good times cruising.
