A couple of weeks ago, I saw a tweet from Berlin Tourism that said they’d mail small pieces of the Berlin Wall to 15 people who sent them a US mailing address via DM (Direct Message – private communication not seen by the Twitter public stream.)

As a student of history, I jumped all over that offer.

Now I have the lovely but sobering little bit of history that you see in the photo in this post.

What a great way for a tourism organization to use Twitter, wouldn’t you say?

It is difficult to believe that it has been 20 years since the Wall fell, but Berlin is commemorating the event in a big way (don’t miss this list from the Guardian of top 10 books about the Berlin Wall.)

I’d love to visit myself some day – there’s been a lot of buzz about the city around the Web lately.

WorldHum mentioned Berlin as a possible expat writer refuge, there’s a new currywurst museum, nice parks, a film festival in the subway, cutting edge fashion,  geeky startups , scenery and architecture (and here’s a detailed transportation update from EuroCheapo.)

But, if I can’t see all that in person, I still have a wonderful souvenir.

Thanks, Berlin Tourism.
