As long as Ole hosts the thing, there is no danger. (He used to be more present in here than he was lately, however.) I've been a part of it since 2005, and especially this year was actually quite lively, with many new high-profile members! 2007, as I remember it, was more or less completely dead, there was an entire "generation" of users who quit at the end of 2006. But we even had a post from Sydney lately, the Ur-founder and former moderator of the forum, whom I thought had gone completely!
What I find funny - as eiger said - is the different types of activity. There are those who leave one or two contributions, and then disappear again forever. Some have prolific outbursts, producing dozens of posts within a month, and then disappear too, only to re-emerge with a similar outburst two years later. There are those who have been members for ages but have, all in all, not posted on more than twenty occasions, those who provide a small but constant trickle of contributions for many years.... and there are the sheer maniacs, for example our very esteemed Australian mate (you know who), who has produced, in half a year, as many posts as I (for one) did in nearly four years...
