I just recently bought my first road bike since I was a teenager (when there was no such thing as a hybrid).
I had been riding a hybrid for many years, and prior to buying the road bike I was only riding on multi-use trails and paths that can have gravel and dirt mixed with paved parts.
A hybrid is great for this type of riding since the tires are wider and the riding position is upright. But then I realized that I was getting bored with riding on the same paths all the time and dodging people with children and walking their dogs, so I bought the road bike in April and love it (have put 1,300 miles on it.)
So my recommendation is that if you're going to ride on paved roads mostly and only occasionally on paths then go with a road bike. Keep in mind that a good road bike will cost more than a good hybrid bike. But if you're putting in a lot of miles then it's best to get a good bike that you feel comfortable on.
I used to make fun of those "biker types" that wear their bright shirts and tight shorts and wear the funny shoes that clip on the pedals...and now I wear those funny bright shirts with pockets in the back, and just yesterday bought the special shoes and clip-on pedals
(I don't wear the tight, lycra shorts though...I wear not-too-baggy biker shorts that I don't feel foolish wearing while walking around in the grocery store.)
BTW, I just joined bikeforums.net, which is a site for bike enthusiasts and you can get a lot of great info there. Some of the older members have an attitude, but mainly the people are very friendly and helpful.
