Hello, I'm one of the new arrivals from the recent May surge, and I wanted to chime in to let you know that not everyone from it is going to forget about it so quickly.
Other folks in this thread have already done a good job explaining the way player-base surges tend to seem to work in GoI (As well as most games, esp. competitive team based games.) Not everyone has interest in sticking with a game, no matter how creative fun or unique, over the long term, especially with so many other titles to pull on their interest out there (Some of them, more easy to learn and succeed in.)
However, if with every ebb and flow of players, some little percentage of the inflow finds they genuinely love the game, and care about it's fate as more than a passing fancy (Such as with myself, and judging by your posts, I would say you too Mister diVario! And many more in this thread and on this forum.) then I wouldn't be too worried about the overall fate of the game. In this way, it builds a dedicated player base of people who enjoy, and in a lot of cases want to improve at the game--and this is a good and positive core player base to have, even if it isn't as large as those of more hulking games... But then, have you seen the horrors in some of those? lol
As far as I've seen in my short time aboard, I've noticed a lot of the older players are genuinely rather friendly and helpful. Hell, some of those early captains I got made me all the more enthused for the game--they were nice, talkative, and funny, and after the matches were said and done I actually thought 'months or years down the road, when I'm in that position, I'd like to be to some new players like they were to me.' Long as the community has these sorts, no matter how slowly it grows, I think it'll be stable. HamsterIV put it rather succinctly.

They can't constantly pump out new ships and weapons--I mean c'mon, they're indie and they already made this crazy game!--but I think in the end this will be all the better. I'm absolutely looking forward to both the announced and unannounced stuff planned for this game in the future. <3
