that's exactly what I did, I decided that nobody was going to build my product but me, so I taught myself Rails, went to developer meetups, and 3 years later I have a nearly finished product and am working full time as a Rails developer ... True it's taken me a long time to learn the skills necessary to build, but it's been a worthwhile journey!
yes, most definitely ... I saw the need for this, and amazingly 3 years later, still do ... whether or not the endeavour is successful, the benefits of DIY'ing it far outweigh the benefits of just paying someone else to do it ...
