Hi -- My name is Chris Dunworth, I'm one of the engineers at Earthcomber. I ran across your discussion here while crawling around the net looking to see how our new release was being received. I hope you don't mind my jumping in with a few comments....
Kwan, you wondered if Spot Guides were required, and the answer is definitely no. They are premium plugins from some of the best travel guide publishers around (Mobil, Moon, Damron), and we think people would be happy with the content in them -- reviews, recommendations, history....even dead celebrities (check out Find A Grave). But the basic service -- which includes the full mapping engine, access to all maps, access to community groups, plus the standard commercial location set -- is all free. And we're always trying to add more locations to this set (in our holding pen we have about 50,000 ATMs to be loaded very soon). Beefing up the restaurant listings is currently a high priority.
And Chris, we're definitely trying to expand the Spot Guide bookshelf. We'll add several titles over the next few months, including some from new publishers. We hope folks find something to their liking there.
We'd love to hear more impressions from your use of the software. Feel free to gripe to us if you have any problems (use the support link on our website, or the public forums in Earthcomber Community). Thanks for giving it a try.
Kind Regards,
Chris Dunworth
