This is probably the correct answer (focus 100% on improving the product). The product is at a state where people like the idea of it so they sign up en masse -- but I'm not sure the site lives up to the expectation yet.
Focus on engagement . Sign ups are almost meaningless if the users bounce and never return. The reason Facebook is so amazing is not just that they have a billion users, it's that they have 80% of them checking the site 5x per week (or whatever). See how many users you can get into the habit of coming back to your site on a regular basis. That's the number that ultimately will drive everything: revenue, long term net…
However when I first built the site, I envisioned more of a LinkedIn-type thing where engagement is relatively low but the value is in the database.
In other words, I don't use LinkedIn very often. But when I need to, it's a godsend (or at least, better than anything else that does what it does.)
Interesting.
