Path is growing at a rate of a million users a week

"Path, a more intimate social-networking app that’s like a personal journal, is now growing by 1 million registered users a week after its most recent launch.
The newest version of Path includes a way to message your friends — for which Path limits to 150 — and send them stylized stickers like other top messaging apps. Around half of Path’s registered users (now at 9 million) are regularly using the app on a monthly basis, CEO Dave Morin said.
Most of the growth is now occurring in English-speaking parts of the population after seeing significant growth in Central and South America — particularly among Spanish-speaking populations — he said. He said the growth started with Venezuela, where Path added around 500,000 users in a weekend, and then spread up through Central America, Mexico and the Caribbean before reaching Spanish speakers in the U.S.
Now, Path is among the top apps on the App Store, and has shown some significant staying power, according to AppData."
