About 5 minutes a month on average. You could probably guess that from my post count. It's a good site, but I mostly specialize in cichlids so I tend to use the cichlid specialist forums most of the time. This would be my first choice for general information on other fish though.
Not nearly as much as I used to I guess things change lol I just dont have hours on end to waste a way on the internet anymore. I still check in all the time though.
