Different people different choices. Some people like to rely on signature campaign while the other people want to work and enjoy other jobs as well.
That is personal choice - as long as the signature campaigns are running one should enjoy it. On a side note - why we are scared of signature campaigns to end? We have lost so many jobs in our real life - we find the other options when one door closes, have faith.
Learn to speak for yourself, and don't generalise people's mindsets. I have been following this thread and I haven't come across a comment that said they rely on this forum for a living, it is maybe a side hustle but wouldn't sustain you right now as a single person talk more of it as a family icon.
Again, you should also know this, there is no signature as forever, it is a privilege that you may enjoy for some time but most of them usually end with PAUSE until the team announce if there will be a continuation, most likely, that use to be the end. Now tell me, will you want to rely on such a stipend as a source of income.
You should also consider inflation especially now that we are in crazy times that almost all currencies are dying to hold their purchasing power, if the federal reserve is showing a CPI of 9%, wonder how you want to manage signature payments to put food on the table. Besides, this is the US we are talking about as a developed country, Lord knows what developing and under developing countries, inflation will be right now.
