Blogger is currently running a survey of it’s users. There are questions about you, your blogging habits, how you started blogging and whether you’ve told others about it, rating things you’d like to be able to do easier and about using news aggregators. Pretty run of the mill stuff, only took me about 5 minutes. I think they should have given you the option to write-in features you want but I guess we already have the ability to put in a feature request in their support system, so I could see not putting it in there. If you use blogger, you’ll see the link on the page where you can edit or post to your blog.
Not sure what Google is trying to get at with this survey but it’ll be interesting to keep an eye on.
