I am about to embark on a long bike journey and wanted a way to post my location easily with no faff using my phone. This plugin does the job remarkably well.

Jetpack app appears to strip the location data however you change the settings, but since the mobile browser experience for WordPress is so good now I just use that. You upload a Featured Image, write your post, Publish it and BINGO there is a little map at the bottom of the post. This is PERFECT for my needs.

In addition, the support is responsive and friendly. Thanks Yann!
