All sorts of reviews of Pownce, a new service that has been compared to Twitter and Jaiku, have delved into the technical arguments about the Adobe AIR client, and how doesn’t Gmail send 20MB files (to Pownce’s 10MB?), and what does a pro account get you, like no ads (what ads anyway?) and 100MB file sending instead, and usually a review can’t end without an assessment of the clausterphobic world of web2.0 personalites. So I can’t compete with that here but let me add my views on the service:

(1) The single most interesting thing about Pownce is the transparent but almost intangible similarity in feel to Flickr, not a coincidence as Yahoo’s photo service is the de rigeur photo site in the web 2.0 bubble (though still not quite the most popular compared to old Photobucket in what Bob Dylan called “America”). Well the similarity in “pro accounts” stands out of course, (I think $20 to Flickr’s $25–but don’t hold me to that I don’t have a pro account now in either service) but use the web site part of Pownce for a while and see if you don’t also sense a vague similarity in look and feel.

(2) Okay, I will wade a bit into the overall debate–Pownce really is sort of a tumbleblog, but it’s not bad but not amazing, at least so far, and could work a bit like Twitter for some peoeple, and some people could use it more like AOL IM, but it really needs to be able to accept incoming feeds (the way Jaiku or Tumblr can) and have external widgets to give updates from the service on your blog. Also they need to serve up a timeline of public updates. You have to click around to find interesting pages–navigation should be done from more angles. (For now, check lead developer Leah Culver’s page for updates about the service because some of these features or others may be added–it’s in invite-only beta right now and the Adobe AIR desktop client is still in alpha.)

(3) Key among the services mentioned is the file sharing feature. I don’t have to run through the history of P2P networks like Hotline, Napster, IRC, Gnutella, Kazaa and BitTorrent here, but some of their varied histories show the vagaries of both popularity and legality of sharing files on certain networks. Pownce, on the other hand, is a new service that may offer a good deal of privacy because it works off a centralized network. Or it may not. But if it attracts a user base that makes frequent use of the file sharing feature (perhaps even files that are legal to share–if that’s even at all possible under the DMCA–I’m not a lawyer) Pownce could differentiate itself from current crop of both short messaging services and P2P networks.
