Textmate was a prime example of what happens when an incredibly popular project is run by a single individual. The fact that TM 2 has flourished (IMO) since being open-sourced, is a good indication that additional eyes are a good thing.
I'm not suggesting that Jon open-sources ST, just saying that reaching out for help is not a bad thing in these one-man-band projects.

So far my company are still the only ones working on it
I just wanted to illustrate how just opensourcing things isn't enough. You need marketing, PR or organic notoriety. And often that takes resources. Once, I met Eben Moglen and he yelled at me for half an hour simply for taking investors for my company. I explained to him that "free software" doesn't solve the economics for entrepreneurs who start new projects. You still need to use resources. Later when I sent him the link to github he said he was wrong but stopped short of an apology. Quite a strange guy.
