I was investigating the bewildering world of trackbacks, pingbacks and blog comments and found that my existing provider, blogger.com, supports backlinks (inbound links to a specific article from a Google search) but not trackbacks.
Then I discovered Wordpress.org which is a blogging tool that supports proper trackbacks, pingbacks (and a whole lot more besides). Although Wordpress is a freely available OpenSource PHP based application, I would need to upgrade my current web hosting to include PHP (for the massive sum of an additional 4GBP per month).
Then I discovered the hosted service Wordpress.com which offers the same functionality so I registered for an invitation email. A little more research unearthed the useful fact that the recently released Flock browser also includes a free Wordpress.com account. I immediately downloaded Flock and got myself this new, shiny Wordpress blog.
I like the blog editing facilities (you can tag each post in multiple categories) which may render that tedious task of manually adding Technorati tags obsolete.
Pros: trackbacks, pingbacks, categories, builtin referrer tracking, immediate WSIWYG preview, automatic Technorati pings
Cons: no direct access to Web server logs and statistics, need to manually import existing blog from blogger, centred formatting, need to burn new feed, lose thousands of readers
