Warning: this blog entry is not about Microsoft and Yahoo!.
I don't know if I am the only one to experience this "bug", but whenever I receive an e-mail from Blogger (a blog publishing system acquired by Google in 2003), be it a copy of an article I just posted or a notification that a new comment has been left on my blog, it is almost always classified as spam by Gmail (which is, needless to say, also owned by Google). Kind of ironic, isn't it?
The "Not Spam" button doesn't seem to work (i.e. it doesn't seem to have any influence on the way Gmail classifies further e-mails from Blogger). Maybe this problem is caused by the fact that I am using another e-mail address for Blogger (which is redirected to my Gmail address)?
I'm generally happy with the quality of Gmail's spam filter, but I still get genuine e-mails in my spam folder, from time to time. Even e-mails that don't come from Blogger. That's the kind of things you don't want to happen with a spam filter. I'd rather have a bit more spam in my inbox. So, let's hope Google is still working on their spam filtering algorithms.
And, yes, if Flickr is indirectly acquired by Microsoft (through Yahoo!), that would suck and I would seriously consider moving to Picasa Web Albums. Maybe. Okay, maybe not, but that would definitely suck.
