IMHO, Java and .NET are only suitable for large enterprise and they absolutely consume resources. You need big machine to run Java and .NET. By the way, the user’s requirements are many more simpler. They just want a simple web interface to back-office data, some of them are in DBMS and some of them are in SAP R/3. SAP Enterprise Portal is too big for this situation. PHP is just enough.

I have so many instant message accounts, says an ICQ, a Yahoo! IM, 2 MSN, a Google Talk, 2 Jabbers, and an IRC. To online on all of them, running standard IMs are not working properly. For example, MSN don’t let me online 2 accounts on my laptop at the same time without unofficial patching. So, I have to choose other IM. Running ICQ, Yahoo! IM, MSN, Google Talk, Jabber, and IRC client on my laptop is not funny thing. They might consume all my physical memory.
