Honestly, I think your personal blog is the best place for this. We have equipment reviews, resort reviews, trip reports etc. If everyone made their own thread logging their personal journey, it would be difficult for the people interested to keep track of. Your personal blog through this site is an ideal venue for this.
huh, I didn't know we have blogs. Well, that's why it would be a subforum, so threads about a particular user are not scattered throughout the site. They are just in one place, if people want to look in there and see what is going on with someone they can. But, hmm, I see what you are saying. You are afraid that if people discuss their trips, equipment reviews etc, in a personal thread, all of that good information would be spread throughout the forum instead of the known subforums. I guess I can see that argument. But I think something to consider is a subforum like this can really increase the interest of casual users to come back more often, than they would just to look up a review. I could be wrong and no one would use it. But if people start chronicling their progress, or whatever, it can increase sense of community. There could always be a disclaimer, that specific reviews should be copied into the appropriate forum.
I'm a member of a fitness site where there is a subforum for journals, they also have the blog feature. Most journal in a thread and not a blog. I don't know, I think people just prefer the format that the rest of site is based in. It also has not taken away from the other subforums discussing reviews and such. The journal or log, becomes more of a daily work things out keep track of things. But I don't know, in this case maybe you are right. Of course, I usually need to use the search feature to find anything anyway, unless you check the site daily.
What I would use it for, is to keep track specifically of how I'm improving. Changes I've made, whether they worked. Although I probably won't be snowboarding for the next 8 months so it's not so important now
maybe I'll bring it up again next year.
