Twitter Mentions as Comments does exactly what it promises to do – scours Twitter for people talking about your blog posts and silently inserts their Tweets alongside your existing comments. The plugin leverages the power of WordPress’s built-in commenting system – notification, comment moderation, author white/black listing – making Twitter an extension of your blog.
<h4>Features</h4>
<ul>
<li>Searches for Tweets linking to your blog posts, regardless of the URL shortener used (using Twitter’s Search API)</li>
<li>Pushes Tweets into WordPress’s existing comment workflow – notifications, comment moderation, and author whitelists/blacklists work just like any other comment</li>
<li>Fetches user’s real name and profile picture and links directly to the original Tweet</li>
<li>Checks automatically – no need to do a thing</li>
<li>Option to automatically exclude ReTweets</li>
<li>Option to store tweets as trackbacks/pingbacks</li>
<li>Option to specify which posts to check (e.g., 10 most recent posts, all posts, front page only)</li>
<li>Smart Caching of Tweets and user data – retrieves only what it needs to save on API calls and server load</li>
</ul>
<h4>Planned Features</h4>
<ul>
<li>Dynamic resizing of Twitter profile images to fit WordPress theme</li>
<li>Prioritization of newer posts</li>
<li>Oauth Authentication to raise API limit (currently unlimited Tweets, but limited to 150 new comment authors per hour)</li>
<li>Smarter API throttling</li>
</ul>

Twitter Mentions As Comments

Twitter Mentions as Comments scours Twitter for people talking about your site & silently inserts their Tweets alongside your existing comments.

This plugin allows to mention WordPress users in a comment by writing usernames preceded by a character (default @), e.g. @guguweb. 
The mentioned users will receive a notification email with a link to the relevant post.
The mention character (default @) can be customized by a filter hook: <code>cum-mention-char</code>. Put the following code in your theme <code>functions.php</code> file:
<pre><code>add_filter( 'cum-mention-char', 'cum_custom_char' );
function cum_custom_char( $content ) {
 return '+';
}
</code></pre>
And the mention character will be +, so you can mention with +guguweb.
This plugin was inspired by <a href="https://wordpress.org/plugins/mention-comments-authors/" rel="ugc">Mention comment’s Authors by Wabeo</a>. Many thanks to the <a href="http://wabeo.fr" rel="nofollow ugc">author</a>!
