Google's been doing some consolidation of having people sign-in for various services through a common Google Accounts login. Dave Naylor noted this happening for Orkut users last week, and now Andrew Goodman finds it happening to Google AdWords advertisers.
Andrew doesn't like it, as he discusses in our forum thread, Google AdWords Advertisers must have Google Accounts to log in? Neither does Nick and gang over at Threadwatch. Nathan at InsideGoogle feels its a good thing.
As for me, I said in our forum thread I find it mostly positive. I don't want to have to remember a billion different passwords at Google. But to Andrew's main complaint, that he doesn't want his business activities (AdWords, AdSense) also mixed with an account of personal stuff (Web Search, Personalized Home Page), that I agree.
I suspect you might be able to have two different accounts, as long has you have two different email addresses. Overall, I like options. I like the option to have a combined account or the option to have two separate accounts, personal and work.
