I've launched my app back in November and had insignificant user acquisition. I had only one (very helpful) user subscription coming from my HN post (which fell way to the bottom in a matter of minutes).
This was my first web project ever, and while I was proud about what I have achieved (launching a product), I was also disappointed with the lack of response.
Now, on Christmas Eve, I started getting a lot of new subscriptions after a period of relative inactivity. Through Google Analytics I saw the traffic came from Lifehacker. You can see the piece here: http://lifehacker.com/5870288/top-10-under+hyped-web-apps-2011-edition
My app is number 9 - Aherk!, and you can access it @ http://aherk.com. It's pretty simple and unpretentious.
Now, although I'm enjoying my 15 minutes of fame, glory & unspeakable success, I'm wondering what steps I should take to keep things moving. How can I not waste this precious opportunity?
Any input is more than welcome! Thanks a lot.
2. write a blog post introducing the app, thanking all the new users and lifehacker.
3. spend some money on advertising (facebook/google/maybe even on lifehacker) for two weeks.
4. update something in the app and release a 1.x version update for free. then start working on v2 with the goal of shipping as soon as possible. keep your blog updated on a weekly basis with a simple 'status' of how the new version is coming along, with teasers about new features or speed or whatever.
