Thank you, Dave, for bringing this issue to discussion - a very relevant and important issue in my opinion.
Me, first of all I dislike the increasing number of places, where people present their models, inform about new kits, etc. I truly miss the times without FB. The mutitude of FB groups drives me mad. I cannot get the idea of being a member of several groups (as far as I know there are at least 5 groups related to WW1 aviation modeling) and presenting the same photos of models in all of them.
As some have already pointed out, it is a medium completely not suitable for presentation of build logs. Searching for any info older than 2 days is barely possible. And it can be full of trolls and other parasites. IMHO it is a place where the majority of users wants to show up, have their moment of transient internet glory, gather likes and hearts...
I must confess, I am present there. And I definitely spend too much time looking for some information about modeling but it is usually a hard task, you have to scroll through the heaps of useless posts... I do it only because:
1) I know that some of my friends, also modelers, are present mainly there. This is sometimes the only way to be in touch with them.
2) when you sieve the rubbish you may find some interesting news quicker than elsewhere (as was the case with some novelties, for instance from CSM)
All in all, I would be very much disappointed is this forum moved to FB (if that is possible at all). I find this forum as a tranquility refuge from that FB mess and noise. Please, no I beg you, Dave, and us all, let us keep it as it is, we all need THIS place, it is the most fantastic virtual world, let us all preserve it and steadily improve it - for us and for future users. Let us do it here, not in FB or elsewhere...
