I don’t use GMail as my primary address, but it’s a very useful service. It’s lean, fast (if you use the old UI) and it’s portable (duh).
My first GMail account was for my personal use, to get notifications about comments to my blog, etc. As I found GMail to be more and more useful, I opened a couple more accounts, to isolate my private life (and GMail account) from my business life. As GMail allows you to send email using a different ‘From’ field and also reply to each incoming email with the address you sent it from, you can simply direct your GMail Notifier at the main account and forget about managing the others. The problems began once I opened an account under an alias, rather than my under my real name.
GMail Talk (or GTalk) allows anyone who knows your email address to talk to you. That’s very nice in theory, but suppose you don’t want the person you’re mailing using an alias to know who you are. Once that person has you in their Talk list, they will now view your full details, but not those that belong to your alias account, but to the account you are using (your real, personal account)!
And best of all – there is no way to turn the bloody thing off! I’ve emailed the GMail team a couple of weeks back and have not heard from them. Mind your step!
(I never asked for anything like this before, but please link to this post, echo it, digg it… anything! This is too important a privacy concern to keep quiet!)
