The number of +100k users has increased! Why? Because of the ~4000 excellent answers Hagen von Eitzen produced.
All the hard work paid off. Congratulations!
Thank you all for your kind remarks! When I reached the 100k limit a few days ago, I checked a couple of times - of course - to see if someone had arranged a surprise party here at Meta. But either I had overlooked it or this thread got created just after I had stopped looking (could be a time-zone issue). So much as explanation why I didn't express my gratitude earlier.
When reaching a milestone such as this, a bit of reflection seems to be appropriate – especially when the next similar milestone, a million rep points, appears to be way out of reach (somehow it felt like taking about ten times as long to reach this milestone compared with the 10k milestone, I must be getting old). Looking back, I cannot help but notice that ever too often the possibility of easily earning some quick rep points from absolute beginner and homework questions made me answer way too many such questions even though they should not have been answered so directly. Then again, I often find it difficult to obfuscate a one-liner computation into a paragraph length hint. Looking forward, first and foremost, I guess that with no nagging rep goal in sight I may calm down a bit and be more likely to refrain from answering all those rep baits. :)
I also cannot help but notice that the answers that got most awarded by the community („Great Answer“ and „Enlightened“ badges) are hardly ever the answers I take most pride in – or sometimes I cannot see how to justify such prominence over other answers to the same questions that are definitely not worse and yet somehow failed to participate in some inexplicable rep-hype. The lesson to be learned from this is of course that reputation is not everything (or rather: reputation points are not everything).
So once again: Thank you all - I'm no good at speeches and so it is not unwelcome that I already have to step back from the speaker's desk to give room for joriki or Don Antonio in a few moments – give them a hand, folks!
