Hi,
In my spare time I am volunteering for AidWorkers.net, an online repository/forum/knowledge base for those working or interested in humanitarian issues, where I keep their aidworkers blogroll up to date.
We list blogs from aidworkers, and publish an RSS feed with their latest posts. There is a lot of interest on that part of our site. It generates quite a bit of referral traffic onto the aidworkers' blogs (which I have witnessed on my own blog).
Expat-blog is an excellent resource for me, to find new aidworkers blogs from all over, but it is pretty much a manual search process.
So if you are an Expat.comger working in the aid, development, humanitarian, volunteering world, please leave a comment on this post, or drop me private message on this forum or email me directly on peter(a)theroadtothehorizon(dot)org.
thanks,
Peter
