For those who do not know what this Dimdim is:
Dimdim is an Open Source project, which is used for online meetings & web conferencing. It is real-time, rich-media & web based. It allows chatting, talking, slide show, desktop sharing etc.. That's the reason it is popular among Open Source people.
By buying Dimdim for $31milion in CASH salesforce has added one more great product in their pocket. I don't understand how these deals in Cash take place at this higher level!!!
The acquisition took place on 6th Jan 2011..
According to news, salesforce.com got extra userbase of 60000 chatter customers!!! Good Luck Salesforce.com!!!!
