Talk to your customers. Find out what they need. Don't pay any attention to the competition. They're not relevant to you.
Joel SpolskyLast week I was listening to a podcast on Hanselminutes, with Robert Martin talking about the SOLID principles... They all sounded to me like extremely bureaucratic programming that came from the mind of somebody that has not written a lot of code, frankly.
Joel SpolskySoftware development takes immense intellectual effort. Even the best programmers can rarely sustain that level of effort for more than a few hours a day. Beyond that, they need to rest their brains a bit, which is why they always seem to be surfing the Internet or playing games when you barge in on them.
Joel SpolskyUsability is not everything. If usability engineers designed a nightclub, it would be clean, quiet, brightly lit, with lots of places to sit down, plenty of bartenders, menus written in 18-point sans-serif, and easy-to-find bathrooms. But nobody would be there. They would all be down the street at Coyote Ugly pouring beer on each other.
