Anatomia di un tweet

Pubblicato il da

Raffi Krikorian, sviluppatore API Twitter, ha pubblicato sul proprio blog la mappa di un tweet in formato Json:

Notate quante informazioni siano contenute in un singolo tweet: oltre ai 140 caratteri del messaggio vero e proprio troviamo una sezione piuttosto vasta con le informazioni sull’autore e un’altra sulla sua localizzazione geografica.
Tali informazioni sono destinate ad aumentare ulteriormente, vista l’imminente implementazione delle cosiddette annotation. Come spiegato da Read/Write Web:

With annotations, third-party Twitter developers can add any additional metadata to a Twitter post. That’s right, any data. And a tweet can have more than one annotation attached to it. This extra data will initially start off small – Twitter developer Marcel Molina said it will “probably” be around 512 bytes. But over time, it will gradually grow larger as Twitter rolls out the feature and scales up in order to support it. The company hopes to have it end up “around 2K,” says Molina. How developers use that extra space is entirely up to them – there can be one giant piece of extra data attached to a tweet or a thousand tiny ones.
With annotations, Twitter could become a platform for sharing anything, not just 140 characters of text.

Social Networking nelle intranet aziendali

Jakob Nielsen ha recentemente pubblicato su Alertbox, la sua celebre rubrica sull’usabilità web, un articolo che riassume i risultati di una ricerca sull’uso dei social network nelle intranet aziendali:

Perhaps more than any other corporate intranet innovation, social software technologies are exposing the holes in corporate communication and collaboration — and at times filling them before the (usually slow-moving) enterprise can fully grasp (and control) the flow.

Here are some things that might surprise you about the social media initiatives we studied:

  • Underground efforts yield big results. Companies are turning a blind eye to underground social software efforts until they prove their worth, and then sanctioning them within the enterprise.
  • Frontline workers are driving the vision. Often, senior managers aren’t open to the possibilities for enterprise 2.0 innovation because they’re not actively using these tools outside of work. Indeed, many senior managers still consider such tools as something their kids do. One of the dirty secrets of enterprise 2.0 is that you don’t have to teach or convince younger workers to use these tools; they expect them and integrate them as easily into their work lives as they do in their personal lives.
  • Communities are self-policing. When left to their own devices, communities police themselves, leaving very little need for tight organizational control. And such peer-to-peer policing is often more effective than a big brother approach. Companies that we studied said abuse was rare in their communities.
  • Business need is the big driver. Although our report discusses specific tools (blogs, wikis, and such), enterprise 2.0′s power is not about tools, it’s about the communication shift that those tools enable.
  • Organizations must cede power. Using Web 2.0 technologies to communicate with customers has taught many companies that they can no longer control the message. This also rings true when using Web 2.0 tools for internal communication. Companies that once held to a command-and-control paradigm for corporate messaging are finding it hard to maintain that stance.

E’ fondamentale sottolineare come ancora una volta non bastino i tool in sé a creare valore. E’ l’uso che se ne fa che deve soddisfare un preciso bisogno dell’azienda.
