This is just a very simple guide if you are a Facebook user and you keep seeing this strange status updates that make no sense to you.
This is the easiest way to know a status update came from Twitter. It refers to another Twitter account. For example, “Great news article at @mashable today”. The “@mashable” refers to the Mashable account on Twitter (http://twitter.com/mashable).
2) RT / via
RT means “re-tweet”. Re-tweet is the same thing as forwarding an email, but you are forwarding a tweet. When you see something like “RT @seattle20: Don’t miss Poker 2.0 tonight…”, it’s a tweet originated by @seattle20 and re-tweeted by me.
It can get confusing as on this example:
“Don’t miss it! RT @Seattle20: Note to startups! RT @AWSstartups: 4 more days to enter AWS Startup Challenge”.If you see this on my Facebook status update, what it means is that I wrote “Don’t miss it” then re-tweeted from the @Seattle20 account. The @Seattle20 in turn wrote “Note to startups” and re-tweeted @AWSstartups, which in turn originally wrote “4 more days to enter AWS Startup Challenge”. This is just like when you get an email where people have been forwarding/replying and adding to it. The easiest way to think about it is to replate “RT” with “Forwarded from”.
Alternatively, some people/apps use "via" instead of "RT" and they put at the end of a tweet, like this: "4 more days to enter AWS Startup Challenge (via @AWSstartups)". I hate "via" because it confuses the reader in figuring out who's the original author of a tweet.
Oh hashtags! It drives Facebook users insane. Hashtags is a way to tag tweets. But it’s a lot more than that. Hashtags can be used to indicate the context of a tweet: “I’ve been looking forward to the #NBA play offs”. On this example, you can just ignore the “#”, but the author of the tweet meant to say “this is really about NBA”.
Hashtags are more commonly used at the end of a tweet, as in “Just watched some amazing video http://bit.ly/abcde #TED #medicine #future”. There is no pre-established rule for hashtag. Each person uses as they wish, however, on things like events, the organizers promote a standard hashtag so it makes it easier for people searching for tweets on that event to find them by using the standard hashtag, like #TED.
A much simpler way to think of hashtag is to substitute “#” with “file under” and imagine you are organizing your tweets on specific categories. That’s why you’ll see tweets like “I just spent 3h w/ AT&T customer service! #fail”.
Have you seen something like this? “Just <3 Redfin!”. Turn your head to the right and look at “<3”, what do you see? It’s a heart. So just replace <3 with “love” and you are set.
OH stands for “overheard”. That’s a connector between the physical world and the online world. If you see a Facebook status update “OH: ‘I wish the food didn’t smell like socks’”, it means someone heard that somewhere and thought it was funny or insightful and mentioned on a tweet. Usually it's used to protect the identity of the person who said that, and a lot of people use OH hours or days later to make sure the date/time cannot be traced back to the source of the comment.
6) I’m at... / I just unlocked the … badge
That’s not Twitter per se, but it’s Foursquare. You probably heard of Foursquare already and every time a user Checks-in somewhere, he can select to update Twitter with that information. Depending how Twitter is configured to sync with Facebook, that update will appear on Facebook as well (sometimes twice).
7) bit.ly / t.co
As you know Twitter is limited to 140 characters only. That means a link to a news article could consume most of the space you’d have to write a message. To fix that there are services like Bit.ly and Twitter own t.co which make URLs very short, like this http://bit.ly/bB1Hev. Those services are called "URL Shorteners". Twitter applications and services usually do that automatically.
8) #fb / #in
There are two hashtags that don't belong to the traditional use of hashtags. They are directives for the services that sync Twitter with Facebook and LinkedIn. The standard Facebook App for Twitter will post all tweets to Facebook, however there is a Facebook App called “Selective Tweet” that only post tweets to Facebook if they have “#fb” on them. Similarly, if you went to LinkedIn and added your Twitter account, LinkedIn will only post updates from Twitter if they have “#in” on them.
I hope this cheat-sheet will be useful to FB users so they can understand what tweeps (Twitter users) are saying. Now post this to Facebook and help spread the word.
