Lots of startup folks live in fear that Google will eat their lunch. Google, the theory goes, has at least 10 brilliant people working on every interesting problem in software and the internet, and they have a gazillion dollars too. They could release the Google “Click Here for a Fart Noise” Toolbar and a hundred thousand people would install it on the first day.

It happened with Google Calendar. It’s happening today with Google Spreadsheet. Boston-area startups Numbler (which is shockingly similar to Google’s spreadsheet, having live collaboration and instant messaging support) and GroupSharp (agruably more generic) are having a heart attack. Or are they?

The optimistic school of thought says it’s a good thing when Big Company A enters your market. It means Big Companies B and C are going to do the same, soon, and what could be easier than acquiring a nimble little startup? It might have kinda worked for HipCal, which was acquired by Plaxo shortly after Google Calendar launched. Of course, we don’t know how the numbers in that deal, leading to comments like this one by Brad Root on TechCrunch:

It’s almost like you could hear the HipCal developers frantically shopping it around to as many people as possible, spurred on by Google Calendar’s release.

HipCal Dev 1: Dude, Google Calendar.

HipCal Dev 2: Yeah, man.

HipCal Dev 1: If the highest anyone will offer us is $1,000, we’ll take it. OK?

HipCal Dev 2: I’m not a moron, man.

Plaxo: Hey guys, we have absolutely no use for your product since our own guys could make something like HipCal in a few hours (and it wouldn’t freak out come day-light savings time and duplicate everyone’s events), but we understand your plight and we’ve personally pooled together about $900.

HipCal Devs (Uninamously): We’ll take it!

What do you think? Will the BigCos be calling with acquisition offers, or developer job offers?
