I haven't found much use for colonies to obtain resources. If I see one that I want, I'll just spend the extra pop point and build a city which in the long run will be much more useful and the resource becomes much less likely to fall into enemy hands with time.
Has anybody found a good strategic use for them that I'm not seeing, or are they pretty much useless? I see the AIs building them a lot...
