At first, I thought Juan Pablo Tapia was from this url, and I left a slightly snarly response. Juan is for real. His Tapia blog (linked above) is Spanish speaking and from my limited vocabulary in his language, it seems to be a pretty good blog.
Juan, the answer to your question is that the url you sent, leads to one of the lamest excuses for a corporate blog I have seen so far. It is insultingly deceptive in that it pretends to be written by Wal-Mart (just plain folk) employees and it isn't it is clearly, posting after posting being written by the same person. Further it has no comments. Further it has no trackback capabilities.
Hugh, wherever you are--stop doing it. This blog needs your analysis. The world needs to know that Wal-Mart has a blog and it is dreadful. Thanks Juan, for pointing this out, and I'm sorry for my original misunderstanding.
