Believe me, this subject has been discussed on more than one occasion.
Amongst other things, there are two reasons why there is no 'vintage' category in the MTBR classifieds.
1. The number of vintage oriented posts in the classifieds make up only a fraction of the overall posts. There are quite a few more DH or Single Speed related for sale items in the classifieds...yet they don't have their own category either. If anything, they'll get their own category before we will.
2. Having a nitch specific category (vs. a part specific category) thins out the categories and makes it more difficult for people looking for parts to find what they want. For example...If I'm selling a set of Ringle hubs, do I put them in the 'hubs' category, or the 'vintage' category? Chances are, that if someone is looking for 'hubs', the first place they will look is the 'hubs' category...especially if they have no interest in 'vintage' stuff. They miss what they're looking for, and I've wasted my $2.
Personally, I dislike the new format of the MTBR classifieds. I miss the old days when you could post as much and as often as you wanted. It made for a very active healthy market place. The problem is, that as this site grew, so did MTBR's responsibility to make sure it's users were not getting scammed or ripped of. Hence part of the reason for the current classifieds format.
As far as being 'so militantly against anything that even smells like it may be an "ad"'....well, check the forum rules and guidelines.
I like to feel that I let as much slide here as I can. I understand our nitch and how important the search for parts can be. Unfortunately, without these rules, this forum becomes a market place itself, and not a place to share info, our restorations, and our stories.
Trust me, I can be a lot more militant. It would actually make my job easier and eliminate the 'grey area' when it comes to posts with forum guideline infractions. I really don't want to go around editing everyone's posts and having to delete things left and right.
This forum has been a pleasure to be a part of and is grossly issue free.
But you can't make everyone happy all of the time.
