I hate when people send me an email with a .rar (or similar non-.zip) attachment. I realize that rar has some special features that set it apart - but those features are not really very important when you're just talking about sending me a small non-commercial c# project in an email.
I think I will create my own custom compressed archival format, and start sending out .lnc files (which doesn't stand for "lance", but something creative that implies its the worst compression format ever, like "loco nasty compression" or "like...not compressed" or "lame non-zip creation") instead of .rar or .zip. Then everyone who wants to open one of my email attachments will have to download and install my software.
And when someone replies back to me and says - "Can you send me a zip instead of an lnc?" I'll just be like "What?? You're still using zip? Ugh. Dude download WinLNC already, its 2008. I sure hope you're not using that 'compressed folders' crap that is built into Windows like all the other Microsoft sheep." Then I'll post information on the WinLNC website about buying the WinLNC subscription package, and false testimonials from all my "customers" raving about how WinLNC is soooo much better than all the other available tools. Then I'll upload the free trial version to download.com and similar sites and write a script that automatically passes through anonymizing proxies and downloads my software once every 5 minutes.
Before my PowerShell friends think they're immune, soon to follow will be the read-lnc and write-lnc cmdlets.
Are you thinking the same thing I'm thinking, Pinky? I'm going to take over the world [of compressed archives]!
