That being said, I also spend many (good hours) dreaming away while buying all sorts of domain names for my fictitious startups. I found that when using the startup niche as suffix or prefix, the domain is sometimes available. Had plenty of luck buying "git-what-ever".com domains, like git18n.com (though I am not sure how clever that naming really is).
Step 2: Make billions.
Step 3: Buy hotdogs.com with your massive amounts of VC funds^W^Wcash.
This is what Facebook (thefacebook.com), Dropbox (getdropbox.com), etc did.
Counterpoint 2: Domain scalpers will demand ridiculous prices if they believe that you are affiliated with a similar-sounding domain or company.
Ever since URL bars defaulted to a web search instead of just adding www.com to the word the value of a one word dot com has dropped.

Anyone sitting on steam.com right now, thinking that Valve is more likely to buy it tomorrow than they are today is delusional. Domain names and TLDs are becoming less relevant day by day and especially with Valve/Steam's computer savvy, gamer userbase, I don't think they really need steam.com. It could be helpful but if they've already decided they don't want it today then they probably won't change their minds tomorrow.
Valve : Steam : steampowered.com
Stardock : Impulse : impulsedriven.com

Ha! The current owners still have altavista.digital.com - it has some history thing.
