A good rule of thumb: if it works for you, use it. There's a lot of ballyhoo about keeping up with the tech Joneses which is mostly unnecessary. It's the most common excuse I see people using for not sitting down and just building their idea (we teach people how to build their own products at Clever Beagle). Tech always changes. If you're truly successful, at some point you will have to migrate to some new technology. Most concern about "blowing up" is just hubris disguised as optimism.

There isn't, hasn't, and will likely never be a permanent, perfect solution. Every single piece of technology has gotchas and idiosyncrasies. Use what you understand and makes you productive—the rest will take care of itself in time.
