Is it time for a user growth campaign?

Take a look at the Tildes Statistics site. Couple things:

1, and most obvious: there has been a decline in users over the past few days for the first time that I'm aware of.
2: (I was going to make this point before the user decline occurred but it's probably moot now) Due to the scaling of the Y-axis, it appears that there is healthy user growth in the site. But if you look at the numbers, we're talking about user growth of roughly 60 people over the past month.

I know we want controlled growth, and I know we don't want to open it up to the masses. But we also want this site to succeed (i.e. provide interesting discourse and keep people coming back on a regular basis). I don't believe success can happen when growth is stagnant (or, declining!)

I don't think that the conversations are necessarily stagnant per se, in fact there's an impressive amount of thoughtful discussion relative to the size of the user base. But if a given topic is too niche (e.g. MLS football or MUDs, two of my interests), the odds of finding like-minded users to discuss with is obviously lower.

Is it time to consider some sort of growth campaign (one that is not reactionary a la the Reddit API changes) in order to infuse some new life into this awesome site?
