I see 3 things happening in the next couple of years, some of which have already started.
- Consolidation of services - Google is slowly building a suite of applications like microsoft and yahoo. And others who don't have a big war chest to build it themselves are getting others to build it for them (think facebook apps).
- Aggregation of services - Plaxo does a good job of syncing up multiple addressbooks and phone directories. We would be seeing a lot more of applications like these. This would also lead to more openness, and though its a little farfetched, it is possible to see microsoft,yahoo and google themselves providing an option to sync up with others. And while all this is going on, there are smaller services like symbaloo and IM aggregators like Trillian and meebo filling in the void.
- Information Summarization - This might sound new, but its already happening today. Aggregation of services by itself gives you a birds eye view of all the information flowing in, but without additional intelligence you still have to read through all your blogs and emails to understand what is going on. Using a combination of different mechanisms, like your preference settings , information clustering algorithms, NLP/NLG (Natural language processing/Generation) algorithms, it can help you cut through your daily feeds and emails swiftly.
