A Conversation with Dick Costolo
summary
Company moves infrastructure to own data centers and is actively splitting a monolithic app into services to scale. Traffic climbs from 100M to nearly 250 million tweets/day and now sends a billion tweets every four to five days; over 100M active users with half logging in daily and mobile growing ~40% quarter‑over‑quarter. iOS5 integration triples daily signups. Ads stay native (promoted tweets/accounts/trends), selective revenue‑share pilots for publishers, legal policy favors notifying users on government data requests. Public API/search export remains backlogged while engineers prioritize discovery features.
