With Blogger's ability to +mention people, and now also sharing the blog comments on Google+, I'd say that you would have a hard time finding something that can beat it the Google+/Blogger combo for impact. Perhaps this can reignite the Delphi blogosphere, as it has never been so easy to create content and reach a targeted audience.
So, why don't you put on your writer's hat, write about your Delphi experience, and share it with us at the
Delphi Developers Community?
