I consider myself a poweruser. I've been using Maemo since Chinook. All the major apps I needed and wanted got hamered out the first month or so of N900 selling. I'm very hapy with the N900, best device I've ever owned. I hack/develop stuff mainly for my own use in my free time because it's fun.

I soon stopped following talk.maemo.org, because it gets tiring to have a zillion threads where someone asks a question on page 1, 15 people say something offtopic or irrelevant on pages 1 and 2, some kind soul gives a proper and correct answer on page 3, and people fill pages 4-6 demanding an answer.

I'm only vaguely aware of titan's kernel. I vaguely recall someone saying it has ext4 from newer ernels. That would interest me, but I'd need a weekend's time to make use of it, so I've never looked closer. As N900 still is by far the best device I've ever had, I want to make sure it keeps working for many many years to come in case nobody comes out with anything that could be considered an upgrade. Thus I stay far away from the overcloking crap, I don't want to slowly make my device more and more unstable until i becomes unusable.
The current performance is good enough as is, though more ram would be nice. Nothing a new kernel would provide. I've been studying and examining long-term swap access patterns to better understand the 2-6 day slowdown effect, found a cause (which turns out to be the same things nokia/peopleatnokia said delayed pr1.2), and a workaround possibly.

In other words, I'm a happy poweruser, and feel no need to participate in the howling masses' running around at the metaphorical market square from one witch doctor's elixirs and placebos to the next, while people doing genuinely interesting stuff with potential to massively improve things are drowned out or even criticized and mocked for the good work they do.

And yes, I'm probably missing out on good stuff like titan's kernel, but I fee much better not taking part in the bigger hatefest.
