Our GeoPost mashup has been updated. Idea is very simple. Many modern blog platforms (most of them actually) let you publish data by email. You can just send email to some service address and platform transforms it into a new post. For example, in Posterous you can send data to post@your_blog.posterours.com, in Friendfeed it is firstname.lastname@example.org, in Blogger you can set address in Settings->Email&Mobile tab etc.
And our mashup Geo posts lets you create a personalized mobile web application for posting geo related data to your blog. Just set a service email address in the form below and get a link to mobile web application for iPhone, Android or S60 platform. This web application lets you email new postings right from the map - just click on the draggable marker that presents your location. And application automatically adds to email a link to the location. So your posts will have a direct link to some map. It is probably the easiest way for sharing locations, write about some check-ins, lets your readers to see the place you are writing about etc.
Also you can create with this mashup your own emergency communication tool. You can predefine not only email address for sending your location but a phone number for SMS too. So you will be able to share your location via email/sms just in one click.
Mashup creates a personal link for your geo-sharing application as well as QR code for loading this link right into your mobile.
For gmail users mashup supports Google Buzz posting too.
