This plugin is totally an experiment inspired in part by @techcrunch, and in part by how useful I have found some of this stuff to be on @Twitter, and also just to see the different ways one can use WordPress. (Update: this plugin seem to only work on WP2.5, so I’ve upgraded.)

If you haven’t guessed already, you soon will. Yes, I’ve implemented @ replies for WordPress. It looks in the local users (usernames and nicknames, like @singpolyma) first, then in the names and descriptions on blogroll links, the it checks if you are trying to use a URL (like @singpolyma.net) and, finally, if none of those yield a result it checks if the string is a valid Twitter username. It produces semantic markup for an @ reply and “person tag”:

<span class="reply vcard tag">@<a class="url fn" href="URL">NICKNAME</a></span>

Then, the plugin sends trackback pings to the URLs, to let the people know you’re talking about them. The plugin also implements trackback receiving on the WordPress main page so that users can receive these pings.

Not to stop so short, the plugin also implements #hashtags. What that does should be fairly obvious.

These features work in posts *and* comments.

I have updated wp-diso-actionstream to 0.45, changes include:

• Fully tested WP2.5 support
• Fixes for Last.fm support
• Better microformats output

I have updated two of my DiSo plugins: Profile and ActionStream.

The profile updates mostly involve some code cleanup, a page here documenting it, and a new API to add permissions options to the permissions page.

The ActionStream update is a bit more extensive:

• Support for coComment
• Code cleanup, of course
• RSS2 output option, linked from the stream output (add &full for a different view)
• Reportedly working in WP2.5 with a patch I accepted
• Better Safari support
• If you disable showing your service usernames they are also hidden in the collapsed items
• Abitily to set permissions on updates from each service (if wp-diso-profile0.25 is installed)

I’m publishing two plugins today.  The first is pretty simple in what it can do for users directly – the XRDS-Simple plugin allows users to delegate their OpenID to their WordPress blog – basically letting you log in on OpenID enabled sites using your blog address, but without needing to run your own provider.

On a far geekier level, the plugin allows other plugins to add XRDS-Simple services and other information (such as OAuth Discovery) using a progammatic API.  A brief example of this API is on the plugin’s page.

I am also releasing a more DiSo related plugin – WP-OAuth.  This plugin enables interacting with WordPress authentication using the open OAuth protocol.  This could be exciting if combined with AtomPub or another protocol / format supported by WordPress or another plugin.

I’m updating too fast.  This release brings some improvements to the UI for adding services.  There are also now options to use the plugin as a sidebar widget or with at easy-to-include post/page tag.  This release also brings the recognition of a requirement of PHP5.2.0 or higher (after much debugging with James Kirk).

And, as always, bug fixes!
