There were a few posts that garnered comments this week, so I will list them all.
Anonymous reader 2 counters this by saying, "To use Nepomuk, Akonadi, and Strigi you'd need to have some kde libraries : x11-libs/qt-qt3support. This probably means you have kde installed and lxde."
As anonymous reader 3 points out, "If someone really wants, it's possible to even run a KDE main component (like Konqueror) in a Gnome desktop (say Ubuntu), provided the necessary infrastructure (in this case, among others, kdebase) is provided. That, of course, defeats the idea of economy and the practical results desktop integration brings."
Finally, anonymous reader 4 explains, "Besides, I don't see that lack of identity as a problem, and something rarely mentioned: the main advantage of OB (and LXDE) is not really lightweightness,but customizability. No other DE is even a match in that respect (except maybe some tilling WMs, but those generaly require you to know some programing language)."
