Your Mom is Not a Valid Test Market

Exactly. I'm starting a company soon, half of the software I plan to sell is software my mom asked for. I know the software I build is good because my mom likes it. However, the way my mom likes my software is she uses it to fix the problems she used to complain about. And if she sees something I need to add, she tells me.

I know what she thinks about the software is skewed because it was built by her son, but I also know she used to say, "I wish I could do this" and now she says "Hey I used your program again today, I'm so glad I don't have this problem anymore." The article is right that you can't use your mom for your typical survey, but she can have a more valuable place as a beta tester, someone you can actually watch use your program.

On the other hand the article does have a valid point. "My family says they like it" is not a confirmation your software is good. It reminds me of when I watched American Idol and the horrible singers would say "Well my family says I sing well."

"Nobody embodies your userbase better than your mom"

That is not a universal truth.

Is your mother computer literate? How does she use web applications and her computer? How does she connect to the product? What niche does the application fill in her life, and is it truly a superior alternative to another product in her life?

What the article is getting at is that friends and family often show extreme positive bias. If you really have to use your friends or family as a feedback group, you'd be best off not telling them you built the application at all. If you're like "hey, check out this thing I found, it might be useful for you," you can get rid of some of the "My child/sibling/cousin/friend built this!" bias and instead only have to deal with the lesser bias of "My child/sibling/cousin/friend referred me to this product."

I agree. That's an overused joke. Just as you shouldn't ask for criticism from friend or family, there is also a simple rule about being funny: don't repeat jokes. Unless you are using it in a new or clever context, or otherwise making it fresh, don't ever try to get a laugh from strangers by repeating anything they've already heard. Your friends will piss themselves laughing at your Zoolander impressions. No one else will.

Maybe I'm the exception, or maybe this is a cultural thing (I live near Berlin), but ...

I'm in the lucky position to have friends (and lots of family members) who are bluntly honest to me.

Your mom goes to college.
