I think it would be a good thing to offer. As noted by others, not every speaker is going to be interesting to every member every time.
I find that I try to go to the speaker portion with an open mind. I've had ones I thought would be interesting that weren't and others that I went only "because" and I found them fascinating.
You never know what will appeal, and if the speaker is good at presenting to a varied audience, they will find a path that has some appeal, at least part of the time, to everyone.
