I'm putting this here because it feels a little too grumpy for Walt at Random...
Early last year, I was coaxed into doing an article for Google's fledgling Librarians Newsletter. No pay but presumably lots of publicity and all the resulting wonderful things that would come from being associated with Google.
The article was a little tricky. I had some issues with how Google was handling Google Book Search at the time, and included those issues in what was otherwise a favorable piece. The folks at Google didn't use the article right away. They suggested using it in some other arena; I suggested taking it back and using it as I saw fit. Eventually--several months later--they did use it, and added a comment noting that they were fixing some of the issues I'd raised (which they did).
OK, fine. I got some nice comments about the article. I have no particular indication that there were any other direct or indirect positive results. The piece came out right around the same time as the OCLC-RLG merger, a time of some considerable personal uncertainty (which continues), so maybe I missed them.
More recently, Google gave up on the Newsletter (as far as I can tell) and started a blog (instead?).
The blog has a sidebar with blogs that Google recommends.
It's an interesting list, both for its inclusions and its omissions.
In the future, I will be more mindful about contributing free writing to a commercial organization.
