ReTargeting : Creepy or Practical? @retargeter

Dang... been a minute since my last post!  Anyway,  ReTargeting :  If your not familar it's a relatively new application/technology from folks like ReTargeter,  that get users back to the original site they were checking out.  That's a really crappy explanation.... so let me explain how it happend to me and why I'm not creeped out,  and instead delighted.  

So I'm booking a flight to San Jose (Bay Area) next week on Kayak,  just checking out prices, availability,  ya know the normal stuff.  I didn't book it yet 'cause I'm still finalizing meetings.  After checking it out and getting a ballpark I went on my merry way to surf the interwebs.   Well this morning when I go to login my calories for breakfast (yes,  I am a freak)  I see this :  

Wow....  not only is Kayak on there but so it the destination San Jose (albeit, the wrong one) but a San Jose nonetheless.   Is Kayak following me around the web?  Are they watching my every step?  Perhaps....  am I creeped out?  Not really?  Like I've mentioned before,  as long as they're not spamming me,  or putting irrelvant ads in front of my face,  I'm good with this type of marketing.  Some buddy's gotta make a buck right? 

Besides... when you're not doing anything creepy on the web,  there's no real reason to be concerned right?  I mean as long as the cookies they're dropping on my system don't have access to financial stuff or whatever,  I think I'm good. I'll probably have something totally weird happen like a Kayak representative show up at my door asking me to complete my booking,  but until that happens... I'm OK with ReTargeting.
