# Target Audience?
When you look at who is using trello right now you will find mostly agile teams, startups, freelancers, engineers, designers who do software development.
IIRC this is also the reason it originally got built. The team wanted to scratch their own itch and I think they did a good job.
I like trello a lot. I dig Joel and joelonsoftware and am curious what the future holds. I hope it won't end up as a misunderstood tool by trying to be everything to everyone.
# Niche vs Horizontal
If you are interested in the trade offs related to going niche vs going horizontal I think 'Crossing the Chasm' and 'Inside the Tornado' are great books to read.
# Disclaimer
I'm working on https://www.blossom.io which has a feature set similar to trello but is aimed at people who deeply care about product development.
