Mashable posted this question on their Facebook Page and the response was a resounding "Hell No." Going through the comments I counted the following somewhat surprising results:
I've found the commenters (commentators?) on Mashable's Facebook postings to be a fairly inane bunch, but I don't mind having a back-of-the-envelope view of their sentiment. And, given my relatively low opinion of the quality of their responses, this is my deduction: basically the idea of "Share" needs to be caveated (again, not a word).
1. Would I share purchases to my network of friends?
My Answer: It Depends (which in this case I think equates with "sometimes")
If I just bought a book that makes me seem smart or clever, why the hell not? I've seen people proudly announce purchases quite frequently.
2. Would I share purchases to BRAND PAGES that I already LIKE (ie., I'm already a fan of on FB)?
My Answer: It Depends
Given that I'm a fan of Ralph Lauren, would I want to let that page
know that I just copped some new gear? Fans do that a lot already, I
read pages fan-comments regularly.
3. Would I share my location to BRAND PAGES that I already LIKE (ie., I'm already a fan of on FB)?
My Answer: It Depends
Fan-dom of brands is huge and growing. Mobile / Location Aware couponing is often a brand's first foray into Location Based Services. Foursquare is banking on that model. Cross-channel marketing hopes to tie online purchase-intent with offline conversion. It's projected that 50% of all offline sales will be driven by online research in 2011. Etc.
4. Would I share my location to my network of friends?
My Answer: Yes / It Depends
People seem to love doing this on all sorts of other services, so why not through Facebook?
5. Would I share my location to GROUPS or EVENTS that I'm already part of on FB?
My Answer: Yes / It Depends
Groups on FB don't seem to schedule reoccurring events (I don't see a lot of DJ parties or after-work sports teams using Groups, for example), but there are lots of Invites and Bars
and Bands that people "ACCEPT" or "LIKE" and I'm sure posting your location to these will make sense to some users.
So, my conclusion is that, like their adamant rejection of UI changes to their profile pages, newsfeed features and every new bit of functionality, the FB community is not particularly adept at knowing what they'll end up using. And maybe it's easier just to repeat "no" than sit back and think, "well, maybe, yes."
