Today I read this amazing post from Chris Messina writing about slashtags, that I called the TwitterTags 2.0 so the new Twitter microsyntax.

What are the SlashTags?

Sure you might have never listened this word, but you can understand I’m speaking about using slash “/” in tweets. Who comes from IRC world, already knows that slashes are commands ( Slash + a word like /join ). Here examples of using SlashTags. There is a project about this new kind of microsyntax, you can collaborate or just read all about Slashtags in this wiki

/via – to say from who you get a content

The via pointer is like “RT”. Already used with “(” and “)” like “(via @nicolagreco)”

Is it time to start switching to HTML5? http://bit.ly/7Tn282 #html5 /via @woork

With the /via pointer you can save one character.

/cc – to indicate someone you want to direct a tweet at

This is like in emails. You use this pointer as carbon copy.

I miss my deadline! /cc @wolly

That’s useful for people that follow lot of users and can’t read everyone’s tweets. So you can get their attention using cc.

/by – to cite or quote someone

Ok this, which might appear same as /via or RT, as Chris says in his post, it’s used to quote or cite someone, so it’s not like retweetting.

make yours spirits bright. wish. /by @stefigno

/thx – to thanks someone for a tweet

This is a funny pointer, we might use to thank someone for a link, for a tweet or everything else.

Bugs fixed! /thx @dottorblaster

Given I use a lot FriendFeed, I would like to add to the Chris list /like. To put a “like” on a tweet. Anyway, we just can use slashtags as we want, like commands giving to pointers a kind of sense, and not just using them as hashtags.
