Getting users 
pclark: our first 1000 users:via our blog talking about what we're doing and why (= good for SEO, engagement of community)PR though you'd be surprised at how little an effect this makes typically though, you gotta really target / be lucky. Tip: DaringFireball = iPhone app sales.Twitter - great to engage users of competitor products (sorry) or people musing aloud wishing your product exists (it does! they just haven't found it!)Spin off sites - I really love these. Do a simple project (= 1 days work) that'll get on the reddit home page or become a mini twitter hit. works really well for getting users, then convert them from the spin off site to your site. if you're a good product manager you can make this work wonders. this might be a widget (duckduckgo style) or a tshirt or mugs, or an actual service.
