According to an article titled, "Blogging's Cure for the Expat Blues," there are. Blogging has been around for about 8 years, and according to the Pew Research Center there are current estimates that the U.S. now has 8 million bloggers, or 7% of the 120 million Internet users. Worldwide, that number is higher still, although other countries aren't seen as being as blog-happy as the U.S. Many of these bloggers are people who have just moved to a new place or country and have no connection to home except by blogging. They find solemnity in blogging. It is their way to cope with the new culture, and by blogging they are also able to make new friends around the world who find themselves in the same situation.
Blogging costs are relatively low (more to start your own blog site). You just need a computer and an internet connection, and the benefits are proving to be great for many. However, the article does mention that although blogging has great benefits for some, they shouldn't let it replace real life. The opportunity costs given up to blog might be greater than they know if they don't get out and experience the new culture.
