My son is an exchange student in Stockholm and we talk to him a couple of times a week by Skype. We even have one of those nifty little Belkin Skype phones so we can talk untethered to a computer (we could have bought a lot of phone calls to Sweden for the cost of that phone, come to think of it).
This morning I was about to make the connection when I noticed that my brother's ID was showing him available. Rob and his wife are the co-country directors for an NGO's Sudan operations. They recently moved to Juba in southern Sudan from Nairobi to be closer to their work, but when I called him this morning they were in Khartoum on business.
He said that he had just finished buying a snow blower in the Twin Cities that he located using Craiglist and negotiated the purchase on Skype. Their home in a St. Paul suburb is rented and the renter had reported to him that the old snow blower was kaput. In Khartoum when that happens? No problem in a flat world. Link to Rob's blog. --Dennis
