Seth Godin always reminds me that it is impossible to please everyone, and as a result focus on people who really love and support your work.
The SlideMagic app and template store currently are small retail businesses where I am also in charge of customer service. And as a result, service at the moment is at the highest standards, you get a pretty experienced presentation designer to fix charts for your for $1 if things are not right.
Still, now and then you get interactions with clients who talk to you like the hotline of a major airline rather than a mom & pop store, requiring immediate refunds or else…
Hopefully one day SlideMagic will be big enough to merit an airline-size customer support desk, in the mean time I continue to develop things with followers who support me.
