I followed my friends' photos on Flickr when Facebook was still a php website for Harvard grads...
This strengthens your point however; first is overrated.
If you can't be first with an idea, be the first in a category. If not create the category and be the first in it.
I find myself using the filters less and less now I have a 4S.
I couldn't easily find any contact info for you.
Mine is [email protected].
Also, pretty sure PicPlz came before Instagram, and for a long time had more users (must suck to be those guys right now).
I kind of figure they had simplicity on their side, combined with an initial target market of niche/boutique/hipster/grunge/retro, and the cherry on the cake was Facebook seeing them as a growing competitor in the photo sharing biz (that would have also added a threat to the value of their upcoming IPO). /2c
Flickr failed to get into mobile partially because of Yahoo's interference -- but perhaps our approach was too complex for mobile. In the early days of Flickr, it was incredibly absorbing - people would waste hours on the site, just like Facebook. But that may require a bigger screen and more free time than someone has when they are on the go.
Flickr is to Instagram as Facebook is to Twitter.
Yahoo should have purchased both FlickIt Pro and FlickStacker, perhaps changed them to white with a designer feel, and marketed them as Flickr Social and Flickr Pro. (Seems to me the two markets of users Flickr serves are people there for the photo community, and there for dealing with publishing high volumes of photos.)
FlickIt Pro opens to a "People" tab, with incredibly easy UI. This focus on people sets it apart.
FlickStacker is an incredibly full featured uploader and Flickr photo manager. I was able to post and manage ongoing full quality photo sets during a recent trip to Corsica using just my iPad and this app.
Flickr also should have worked with Apple to build a Flickr uploader built-in, as Apple did with Twitter. Twitter or Facebook is great for snapshots, while Flickr is for photography.
In addition to your analogy, I'd suggest that Flickr is to TwitPic as Photography is to Snapshots. The photography market gets overlooked (though 500px is moving in) but both pro and amateur creators appeal to Apple. Instagram and Facebook are not about photography, so Flickr could still own that term.
Today, I'd no longer argue for a button to "upload" to Flickr. I'd argue for pushing the Apple iCloud Photostream to a Flickr Photostream mirror set that users can rename, then letting Apple's native Camera or Photos app built-in share interface toggle the pre-uploaded photos' visibility to Family, Friends, and Public. This lets the sync happen in the cloud, decreases friction, and encourages more Pro accounts since users could run out of 200 free photos quickly.
Actually, Facebook was first. They've been calling themselves the biggest & best photo sharing app for quite some time now; long before Instagram existed. By this Author's logic, Instagram shouldn't have bothered.
Being first is good, but being great is better. That was the motivation behind the Mac OS, the iPhone, the iPad, etc, right? None of those things were the first in their categories.
