Multiplatform stuff to consider when planning an expedition

Depending on the length and remoteness of your expedition I would suggest that the best way for your to proceed would be to have someone at base who you can upload packets of information to, using a sat uplink, as the year progresses. I'm actually looking into doing a similar sort of thing from the Arctic and Antarctic - even more logistically challenging, and using Iridium Modems and Begans to get the data across. Assemble your clips, text etc, in the field and uplink these packages in the evenings to base, who can then do the final posting, youtube uploading, Google File generating etc. They can also monitor comments from visitors to the site.

LONG WAY DOWN
You might want to check out Long Way Down, a Ewan McGreggor Project: www.bbc.co.uk/longwaydown and http://www.longwaydown.com/ to see how they did it. Which was similar to how you propose, They used 3G whilst in Europe but from most of Africa they uploaded to base with a Satlink.

I was at a talk about their project and they said the following: Web content/podcasts were "little moments of fun" mostly recorded on Mobile phone but also DV shot. 3G sent direct within Europe – Africa has no coverage, so satphone was used there. They sent in daily reports from the road - 115 clips in the 85 day expedition, 30-60 seconds each. Daily, or regular updates is very important to maintain an audience. They produced what is known as "Mashable content" allowing people to take bits away and embed on their own websites. Cycling websites etc and sites that were doing similar journeys. This allowed the word to spread about their project.

SUBSCRIBERS, PODCASTS & YOUTUBE
I would also set up an RSS feed so you can have subscribers to your blog and create a video/audio cast for iTunes. Youtube is an easy and free way to create a subscribable channel too. Photoblogs are very popular - using a service like Flickr or Panaramio, and along with Geotagging (see below) you could get the best out of these sites and see your photos on their map interfaces.

You might also want to consider tapping into the social network groups, namely Bebo, Myspace and Facebook - Bebo is about to break into the media market with the launch of a teen drama (Kate Modern)

I have written a quick guide on how to create a podcast here:

GEOTAGGING & GOOGLE EARTH
If you going to be travelling around much I would strongly urge to get into geotagging. We cannot underestimate how important this will be in the future, and how exciting it is at present. Ashley Highfield, director of BBC Future Media & Tech, said as much at the BBC Vision Multiplatform day.

Read my article about a little gadget that I use - cheap, easy and very effective. From this you can create a Geotrack which can be viewed on Google Earth (or any other global interface) as in the image below (you can also embed video and audio) - puts your media in a geographical context.

Also see why I think Geotagging is the next big thing.
And Geoblogging (put your blogs in a geographical context)

Not only does Geotagging put media and place together but it also allows you the capacity to leave "virtual graffiti" so people can access media about a location when they are at the location - using the power of Wifi or mobile internet. (see the mscapers project by HP).
Hope that helps,
