The problem I see here is why would I use these products when I can just create my own? But maybe it would also help to organize them by category and capabilities, try to sell them more on what they solve..
I guess you are right, and many of the people here would be able to build something custom. That's not the case for the majority of the people. Even more so when hosting is involved.
I dunno - it's very unpredictable. We can't tell where this will be in 2 years.
