ENTRIES TAGGED "Twitter"
Twitter could be so much better than an advertising company
We can now gather from Twitter’s IPO that it’s fundamentally postured as an advertising company, but its real value isn’t in advertising. Twitter’s most fundamental value rests squarely within data analytics. However, just because Twitter could make a lot of money in advertising doesn’t mean that advertising is where it should concentrate the majority of your efforts or where its most fundamental value proposition lies.
More specifically, Twitter’s most fundamental value is in the overall collective intelligence of its user base when interpreted as an interest graph. Think of an interest graph as a mapping of people to their interests. In other words, if you follow an account on Twitter, what you’re really saying is that you’re interested in that account. Even though there’s lots to be gleaned in all of the little 140 character quips associated with a particular account, there’s a good bit you can tell about a person by solely examining the accounts that the person follows.
Computing Twitter Influence, Part 2
In the previous post of this series, we aspired to compute the influence of a Twitter account and explored some relevant variables to arriving at a base metric. This post continues the conversation by presenting some sample code for making “reliable” requests to Twitter’s API to facilitate the data collection process.
Given a Twitter screen name, it’s (theoretically) quite simple to get all of the account profiles that follow the screen name. Perhaps the most economical route is to use the GET /followers/ids API to request all of the follower IDs in batches of 5,000 per response, followed by the GET /users/lookup API to retrieve full account profiles for up to Y of those IDs in batches of 100 per response. Thus, if an account has X followers, you’d need to anticipate making ceiling(X/5000) API calls to GET /followers/ids and ceiling(X/100) API calls toGET /users/lookup. Although most Twitter accounts may not have enough followers that the total number of requests to each API resource presents rate-limiting problems, you can rest assured that the most popular accounts will trigger rate-limiting enforcements that manifest as an HTTP error in RESTful APIs.

American Express turns Twitter into an ecommerce platform
American Express announced an enhancement this week to its Sync with Twitter feature — users can now buy things with a tweet. Tricia Duryee reports at All Things Digital that all users will need to register to participate, even previous users of the sync feature, in order to provide a delivery address for purchased items. Once registration is complete, Duryee says, the purchasing process is pretty straightforward:
“For instance, participants will be able to buy a $25 American Express Gift Card for $15 … by tweeting #BuyAmexGiftCard25. American Express will reply via Twitter, asking the user to confirm the purchase in a tweet. All products will be shipped via free two-day shipping.”
PayPal launches a card reader, AmEx teams with Twitter, and the smartphone tipping point is mere months away.
PayPal introduces its own credit card reader, AmEx asks you to tweet it out, and Asymco visualizes the smartphone market. (Commerce Weekly is produced as part of a partnership between O'Reilly and PayPal.)
iPhone gets cracked, Twitter gets picky, and Internet connectivity gets disrupted.
In the latest Developer Week in Review: the iPhone fell to attackers, Twitter shunned their developers, and the Internet proved not to be as robust as one might hope.
John Adams on Fixing Twitter: Improving the Performance and Scalability of the World’s Most Popular Micro-blogging Site
Twitter is suffering outages today as they fend off a Denial of Service attack, and so I thought it would be helpful to post John Adams’ exceptional Velocity session about Operations at Twitter. Good luck today John & team… I know it’s going to be a long day! Update: Apparently Facebook & Livejournal have had similar attacks today. Rich Miller…
If there’s a site that exemplifies explosive growth, it has to be Twitter. It seems like everywhere you look, someone is Tweeting, or talking about Tweeting, or Tweeting about Tweeting. Keeping the site responsive under that type of increase is no easy job, but it’s one that John Adams has to deal with every day, working in Twitter Operations. He’ll be talking about that work at O’Reilly’s Velocity Conference, in a session entitled Fixing Twitter: Improving the Performance and Scalability of the World’s Most Popular Micro-blogging Site, and he spent some time with us to talk about what is involved in keeping the site alive.
