I didn't say anything about "experienced cyclists." I don't think you have to be experienced to know what you want. If you want to commute to work on a bicycle, there are many things you already know about what you do want and don't want. Same with any type of cycling - touring, cyclocross, road, race, mountain biking. If people are laying out criteria for a bike, they have done some research (they may not have much experience) but apparently not enough to identify an appropriate price point for their planned purchase. So, they think that people in the forum can advise them on a bike based on a fairly arbitrary and low budget.

And yes, there will be many suggestions and recommendations. Only for the OP or someone else to comment, but it's over $X amount. So it is frustrating when someone feels like (through their own experience) that they could suggest several bikes that would meet the criteria, but those bikes are over the $ budget $. And... most of the available bikes that meet the criteria are over $X amount. So... what do posters do? They suggest bikes that don't meet the specifications or criteria. And then the OP asking for the suggestions goes out and buys one of them. So in a case like that, it was the $'s driving the decision, and not really the goals and objectives that the rider started out with.
