This is a nice feature on top of twitter to call your followers to say Hello, but is it effective?. The service only allows 2 minute calls, that means if you call someone and say who you are itâ€
The service has some more limitations apart from time limit, both the called and receiver should be using Jajah and both are following each other on twitter. Both has to follow each other is necessary otherwise it will be abused and becomes an annoying feature.
To initial a call twitter users has to send a tweet with @call, for example @call @twittername, then both the phones of the users will ring and they can talk for 2 minutes.
Facebook got the voice chat feature with Vivox and now Twitter has a phone call feature, although this is not a true voice chat, and we may see similar services to popup on every social service out there. Will you be using this service, what do you think of it?.
