Six Apart updates TypePad blogging service

has enhanced its hosted blog publishing service with features that tap into the popularity of individual social profiles and online-activity notification feeds.

Six Apart expects that the improvements, scheduled to go live on Friday, will help its publishers form tighter bonds with their blog visitors.

"One of the trends that underlies what we're doing is that our bloggers increasingly are asking for ways of building stronger relationships with their readers," said Chris Alden, Six Apart's CEO.

One of the changes is a revamping of a years-old authentication and profile system called TypeKey, which in its new form will be called TypePad Profiles.

With this feature, bloggers and readers will be able to create rich profiles that not only contain their photos and basic personal information but also incorporate links to their memberships in other sites.
