That sounds pretty good to me. However, all the hacking I hear about in relation to startups is either a) UI design (e.g. Wufoo) or b) server scaling. Server scaling is about as boring and unhappy to me as you could get without mandating that it be in Java; UI design is better, but still not appealing.
There are obviously exceptions; search engines come to mind. But overall, the average successful startup seems heavy on nasty little problems and light on big, hard problems. Is this perception correct? Anecdotes for or against?
In building our startup I haven't come across any monumental, super mathematically/computer science involved problems, but it's still been extremely challenging and fun. I'd say the challenge/fun comes more from trying to do all the things you listed at once, instead of any one of them singularly.
If nothing else, CSS and IE will teach you patience.
If by "startup" you just mean "implementing the Web 2.0 idea-of-the-week", then yeah, I agree UI is usually pretty important.
Why "other than search"? Seems to me that at least half of the reason Google won was because every other search engined was tarted up with "portal" BS. That's UI.
So, since it's clear to me that search isn't one of those classes, and the examples given ("systems" stuff) is the area my startup is working in and I'm absolutely certain that UI is going to be 50% of the success or failure of our company, I'm not seeing any area where UI isn't vitally important.
One of the WFP2007 groups is working on a new language for mobile app development...and they're spending plenty of time on the "UI" even in that case. UI, of course, being anything that involves a user interacting with your system.
I guess someone somewhere in this thread is treating UI as "pretty things on a web page"...but UI hacking is important no matter what you're doing, if you want to sell it.
In the words of Jeannette Wing, the two A's of "computational thinking" are "abstraction" and "automation"
(from http://www.cs.cmu.edu/afs/cs/usr/wing/www/ct-short.pdf)
In other words, interesting hacking occurs when you realize that a certain task can be automated (e.g. writing UIs or administering servers), you create a useful abstraction for it, and then you write the code that performs the task largely automatically.
This is why pg champions Lisp as a great language for startups: Lisp is perfect for building other languages because of its powerful macro facilities, among other things.
I guess what I'm saying is that "startup hacking" is as interesting as you make it. Sure, you can toil away writing similar code over and over again to create various facets of the UI, but the more interesting thing to do is to write the program that writes that code for you.
"A couple of young, talented people, working out of their garage, create a product in the hope that a big company will buy their effort, and make them a lot of money."
Make Something People Want is not fun. The alternative is to go Indy. I'm considering moving to a low-cost country, living a student life, and working on my own projects for a while. If I happen to make Something I Can Make Money From, great. But that's not the point. I'll get to pursue my own ideas, 100% of the time. I'll see just how far I can go.
The UI presents your service, and the scaled out servers power your service, but without the service, all you have are some pretty pictures and a bunch of hardware.
Also, scaling is not a solved problem in the general sense. You have to find ways to elegantly and efficiently solve _your_ problems specifically. I say with confidence that if you aren't willing to be very involved in the scale out of your service, you'll likely design a service that won't scale out.
(For an example of an elegant tool used in scale out, see Facebook's thrift.)
Also, if service agnostic scale out is a small problem for you to solve, I encourage you to get rich by solving it. I'll buy your solution if it works.
If you solve P = NP, your work and reward are high.
If you solve 'My website is having performance issues' the work may be hard, but the reward is getting to do it again next week (if you're lucky)
