Ask HN: Feedback on marketing approach for Ghostpo.st

Hello HN, I'm working on a creative blogging platform that could be used for personal use or business and could use some feedback on my marketing approach, focus and overall site design. The site is live and I should share just a few thoughts.

1. I created Ghostpo.st because I couldn't find a platform that let me upload and share all the digital assets of my life.

2. Ghostpo.st started as a simple photo sharing app but I add the 'Custom Headers' and 'Local Tags' as a way to include value added features I couldn't find on the other social blogging platforms.

3. I'm currently working on some cross browser layout issues.

4. The 'Local Discovery' feature is a work in progress but I would be interested in your thoughts on the overall idea.

Any feedback and/or suggestions on the site/concept would be awesome.

Thanks in advance, Dave
