I've had a new part of my daily routine for a while now ... on top of take vitamins, clean teeth ... I have "check for updates" on iPhone and iPad. I even have a sense of regret if there's nothing new. Even the news that some favourite app has added support for Chinese and Korean is enough to create a frisson of excitement. The AppStore is truly a wondrous thing - even though I may now have to check on iPhone, iPad, MBA and iMac.
Yet, on the web, there's nothing to create that sense that there's something to look at (unless your only source of content is Google Reader). The number of sites I visit just once is a far, far higher number than the number I regularly visit - the 10 most used of which are permanently pinned open in Rockmelt (and before that were faviconised in Firefox). Yet those other sites, just once visited, are doubtless spending money upgrading, iterating, improving user experience, adding content, enhancing functionality. If I only knew.
So does the web need some kind of AppStore? Not to deliver apps particularly, but to tell me when something new has happened at a site that I've visited. Where "new" means an upgrade rather than some new content.
Of course, endless update notifications could drive me madder than Jack McMad of the planet Mad. But, judiciously used, I might return to visit those sites that hadn't enticed me to register properly - but had piqued my interest enough to have me leave something that okayed updates. If they abused the privilege then they're quickly deleted. But, if they don't, they might gain repeat business/
