- Note: Bridgy's Webmentions for blogs gets real-time updates from wordpress.com in order to send webmentions on their behalf.
When commenting on other blogs hosted on Wordpress.com, (even blogs with a custom domain such as gigaom.com), it makes you sign in using your Wordpress.com account.
There is a section on your logged-in view, "comments I made" which is supposed to show you comments you made on other wordpress.com blogs. However it did not show the latest comment I made on a gigaom.com post, despite it forcing me to log in to my Wordpress.com account to make the comment. Aaron Parecki 14:38, 13 January 2015 (PST)
WordPress.com is a blog hosting service with impressive importing and export features. See for details:
WordPress.com provides themes to change the HTML/CSS/JS and general appearance of a user's site. While users can pay for a feature to write custom CSS, they can't change their theme markup. Which means amongst other things, a user cannot specify some markup in a post to show on a permanlink page and not in the post when it's a part of a feed. For example,
WordPress.com doesn't have built in support for webmentions, but Bridgy can send, receive, and display webmentions for WordPress.com blogs. You can also receive webmentions with webmention.io and maybe webmention.herokuapp.com.
On 2014-05-06 it was reported that http://indiewebify.me returned an empty result when attempting to check gabrielscheer.com. That domain is hosted on wordpress.com and it appears that wordpress.com is blocking some cURL requests based on the User-Agent. At a minimum, it appears that wordpress.com is blocking cURL requests with the Guzzle User-Agent.
This issue was previously reported on Github on 2013-05-19 
- curl -i -H 'User-agent: Guzzle' http://gabrielscheer.com/ -- fails
- curl -i -H 'User-agent: indiewebify.me' http://gabrielscheer.com/ -- works
