There are simply so many browsers and devices being used today, it is hard (impossible?) for a site, particularly a small startup, to support everything. I think its important to figure out who your target is. Do I need support on cell phone browsers? What types of interactions do I need with my users? What groups will be my "bread and butter" so to speak? If I'm selling Macintosh accessories, perhaps I don't need to support IE6. I think you have to make some decisions about what you want to support. I really don't think complaining to your users about the browser they have chosen helps. If anything, it drives them away. I do think that no matter what you choose, you should always give your users back something. You may not be able to support all browsers, but don't return a page that simply doesn't work and leaves the user wondering why. This may be easier said than done, but I think its a good middle ground between the complexities of trying to support everything and alienating users by only supporting your "chosen path"
