Probably not a mainstream user

Now, my list is not scientific at all, and is, as usual, meant to be the start of a conversation. What I would do to make it scientific however, is as follows:

1. Talk to experts (hello there, experts )
2. Based on expert-input, design a survey that measures preferences per demographic (gender, age, spending-behaviour, etc.).
3. Advertise that survey on an industry-specific website (Alternatively: use survey to interview people face-to-face during an industry-specific event. Works well as a combo, the first being quantitative, the second qualitative.)
4. Process data into user-achetypes (and expected ratios).

In web-apps, by which I mean a web-utitlity like Facebook of Netvibes, I’m curious as to both the archetypes and, later on, how to deal with them. Generally, you of course have the early adopter and the mainstream one, which, I know, should be catered too differently.

Following is a list of the ones that I would expect to play a role.

• The money-maker: This is typically the most pragmatic of the group, cares about results, speed, and task-specific information, but not so much about elegance and useless information.
• The (early) geek: This, at the risk of generalising, is very much the Digg-, Techcrunch-, and Engadget-audience, by which I mean the typical commentator on those sites. They ask for feature, after feature, after feature, and often ask for too many of them. I call them “early” geeks, because I expect them to be rather young.
• The newbie: This is not the loudest of users, and tend to accept that which they get (as long as the quality is ok). I’m thinking people that use PCs with Vista-home pre-installed. I think that these are also pretty hard to reach with niche-apps.
• The specialist geek: I’m thinking photographers or writers, who have very specific demands of what an app should do and also a certain aesthetic demand. This would be more the Macbook Pro / Photoshop audience. Whether these are a large segment in the web-apps category, I’m not sure. I would expect that these apps don’t really meet with their approval, most of all because they are often free.

What do you think? Were there any archetypes that I missed or is the reality much simpler? (How) do you find out what the user-archetypes for your apps are?
