I agree with @Cornfed - those of us paying will not continue to do so if the free element increases too much. That is the nature of capitalism, and a man should know his limitations.
But I also agree with those complaining of bugs. I read elsewhere from @Martin_Stahl that the site employs 650 people. There are clearly too many working on innovation and not enough on customer support and fault fixing. I am into my third week of not even having an acknowledgement for a bug problem.
A large portion of staff are engineering, from coding the front-end, back-end, and handling all the supporting tools/software. Staffing has to be balanced against revenues.
Regarding your bug, what is it? I may have seen it but don't recall.
Some of us are too BROKE to PAY for the premium membership.
I knew someone would say that.
It's about priorities, as is about everything in life.
I mentioned the $33/yr option: that is a mere 9 cents per day.
Even the Gold membership works out to 14 cents per day.
Each gets the unlimited puzzles some crave. The cheaper of the two gets...well, everything!
If one is so broke they cannot afford these, they might consider spending a wee bit of time each year coming up with, say $33 if indeed what they want is important to them. One could even get that amount in the US on average by donating 1 pint of plasma a year or not eating out once or twice a year. You can earn $ by taking some online surveys during the year or selling items you do not need anymore. There are of course far more ways to come up with these small amounts during the year.
I might add, the prices I cited are normal for the US. In other parts of the world, pricing for membership may actually be cheaper.
If one can't afford 9 cents a day...arguably they have more pressing issues than a need for more puzzles or more game review. I am not a 'life coach', and I am not trying to 'shame' anyone, but what I said only seems to make sense.
