Re: The endless influx of low-quality, low-realism, quantity-over-quality aircraft into FGAddon

The complaint brought up by SP-NTX is one I hear quite often with the 
new FG users I try to help.

This can boil down to simply, how important it is to satisfy the 
expectations.

I believe we have said all or most of what is to say about the point.

Along the decades, we already tried ways and manners to detect "the 
aircraft's everyone like", and I think it is safe to say, this does not 
work well, since we come back again and again on the matter.

Perhaps the it is not possible to "judge/rate/evaluate" the best 
aircraft's ...
Perhaps we should do the contrary, something like creating a 
'FGAddons-B' or anything 'B' that would contain the models who clearly 
yet need development.

'B' as easy accessible than the 'developed one' but clearly labelled: 
"Aircraft still needing (basic) development.

I am sure Emmanuel would not mind. Emmanuel is stating quite openly his 
models are meant to be developed further by other developers.

Albeit, the benefit could/would be double.
1.
Clear away the many 'potentials future good aircraft's ' and offer more 
visibility to those models developers already invested in half of their 
life. :)

2.
FG quality can be built based on better models, whilst the 'other 
models' are not forgotten, but do not obfuscate the good work we all do.

Kind regards
Lawrence
