Need help finding keywords and sectors related to the project

This week we launched www.thedatapond.net and published our first post on IH (here).

Feedback has been positive so far. Maybe we can do something interesting with this project.

But we have difficulties creating a list of keywords we could use to describe the project and to use for research, and to clearly define the sectors to target.

We don't know much about marketing, so any help would make us learn faster.
