I'm not sure how to work this without starting a PHP vs .NET war.
We're at a point where we are planning forward and looking to the future of the business. We've decided that the business will soon split into two parts;
1) The main business concentrating only on web applications
2) Our existing business which will continue to provide web development outsourcing and suppling agencies with websites using our own Agency Branded CMS.
A few years ago I worked with ASP.NET a bit, and liked it, I really wanted to start using it but I couldn't come up with a valid reason of why I should concentrate my efforts on .NET rather than PHP, given at the time I had far more experience using PHP. I believe at the time I found community support for .NET a little lacking in comparison to PHP.
Anyway, my question is. Now we're splitting the business, would it be better for us as a business to concentrate the web application side of the business on using .NET? Really to the client I know there's very little difference and most really don't care how the application is built providing it suites their needs, but I guess I want us to be a little different, everyone these days uses PHP (especially the bedroom coders). I guess in my mind I'm thinking that offering .NET web applications makes us a little different to the competition and opens of the chance of getting larger projects (especially government and corporate).
My biggest issue I guess is that I've used PHP for years, and although I wouldn't say I'm an expert, I can do some fairly good stuff with it. I've used .NET and built a couple of projects using it over the years, but my knowledge isn't as good as my PHP knowledge so I'd need to invest some time into brushing up my skills and improving them. Is the investment going to be worth it? or are we simply best sticking with PHP.
