Picasa+Web=Picasaweb,

Picasa from Google is a well known software for image management + some tweaking options. But when it comes to Picasweb situations turns out murky. Google model for this service is different from many other online photo storage services like Photobucket, Imageshack etc. Picasaweb is like an internet partner to Picas and both are seamlessly integrated, with easy uploading options. Though Picasa is not a necessity for uploading, which means it also have normal uploading options. There is no mention of bandwidth provided but they give user some 250MB, which can be upgraded to 6GB for $25/year, which in itself is a good bargain.
Navigation on Picasaweb is very good, and swift, sharing facility is also great, which is the viral part, like any other such service. There is an option for print ordering also, which is very much in phase with other services. And very much similar to other such services there are all those tagging, commenting, HTML links etc. But when it comes to social aspect it is a big zero. Just to understand Flickr is such a success not because it is a photo storage service but it is very social friendly, you can spend hours surfing on flickr. Go to my Album, and you will not find a single way to search any other album, but my favorites, and currently I am not having any favorites, because none of my friend is using PW and I am not able to search any other album, which mean even I am facing a dead end. They are offering a video upload option, and also an option to uploads friends album, but hey I haven't got a single friend on PW and neither I am able to make any as I am not able to search any.
If you think that there is no way out, then I am not going to buy your view. My logic is pretty simple, integrate Gmail(which now is an open network), Orkut(which is also an open network), Blogger(which was open and will remain open) with PW. And then what you get is a killer application, with killer web service.
Google has really got something wrong when it comes to create social networks around their service. One of the key feature of Wordpress which by many is regarded as a better blogging platform than Blogger is their social nature. Google answer also turned out to be a debacle and Google would soon like to forget it. Google groups is not at the top of chain, and if there wouldn't have been up to blogs then you might have probably missed many of their services.
While Google creates any new service or buy out a new one, you can try their old ones, and comment on this post.
