Just to share an observation...There's some repetitiveness in the types of posts and for true experts, I can see how it becomes less interesting over time.
A suggestion to make the forum better would be to have some well known guest experts post (like a first Friday in the month). Examples/Topics:
* A well known frame builder share his thoughts on what make a great period frame, and how does it translate to modern/today frames. What was it like in the day?
* Know collector/seller (Hilary Stone comes to mind as an example) - Special C&V frame/bike, what make's it special, not-so well known builder. etc...
These types of topics are more interesting and may better engage the true experts and folks wanting to learn. Frankly, as a non-expert - I look for these types of posts as unique opportunities to learn.
I think there are some well connected folks on the forum. Guest posters with an expert panel discussion would (in my book) be pretty cool...It takes out some of the repetitiveness.
Just a thought.
