KDE: Nepomuk and Strigi

[viking60]

I have often blamed KDE for being the most resource heavy Desktop Environment in Linux. Die hard KDE fans keep telling me they have no problems with KDE eating their CPU power.
So I thought I should try to optimize KDE a bit:
On my not so powerful laptops I have noticed that the Indexing procedure can take up to 100% CPU for quite some time. It turns out that Sigi and Nepomuk are working very hard pulling a lot of Juice in KDE.
So I thought what do I need it for? As far as I can tell: Nothing!

From there the way was short to system settings and deactivating both Nepomuk and Strigi. After that I have a nice and lean KDE 4.7.1 behaving well and not pulling that much juice.
And I don't miss a thing!
Does anyone know what I will be missing? Besides eating resources what was it for?
I have seen it explained like this:

Nepomuk initially aimed at two main achievements: 1) the ability to interlink data semantically on the desktop across the applications, 2) the ability to share semantic information with other desktops

Yeha right I do a lot of that
What do you use it for?

You always deliver interesting stuff Jim! Thanks!
I hope the guy finds a project sponsor. And I am confused at a higher level now regarding the nepomuk function. I still think I can do without it in my situation but I can see how others will need it.
Edit:
And I am convinced that it has a lot of potential.

I always turn off indexing. Always. I know where my files are, TYVM (most of the time, anyway).
