For whatever reason I've only ever worked solo. The job that I have now, I was under the impression that I was being hired to work underneath a senior developer and that I'd be able to learn from them/their code. This was actually one of the conditions that I had when I accepted the position (that and I was broke and needed the cash - so I would have likely taken it anyway). As it turns out, the intention of management was for me to replace that senior developer because they were contracted and relatively expensive.

The question I have is, though I've learned a lot in the 2 short years I've been here, am I potentially seriously stunting my learning/progress working solo instead of working at a company with other developers?
