Yes, there is a distinction between exosci and sciforums. Whatever happens, sciforums will remain.
I suppose it's a question of my motivation. I'm at the point in my life where I'm forced to reevaluate what is important to me and where my interests truly are. When I started the site, I was but a young student who was certainly interested in the natural sciences. Alas, a series of events disillusioned me and I now realize that my true interests lie in software engineering, information design, and user interface design. exosci is no longer aligned with my interests.
Now, it's a shame that money is involved at all, but it is. It's not a matter of scarcity at all. I really have no expenses in my life to worry about. However, the collapse of the internet advertising industry means that I'm getting essentially no compensation for the work I do for exosci. I could make more money by begging for money on a street corner (it's really that bad -- and it's worse for these dot-coms that actually have people to pay). And while money is not a very good determinant of a person's worth, salary certainly is an indication of how much society appreciates your work. It's difficult to justify taking time away from one's true interests without recompense.
exosci was always just a little hobby of mine. I did it on the side because I had time to spare, and it interested me.
Anyways, I'm going to California this weekend for a week. I'll be making some sort of decision upon returning.
