Today Google introduced searching into it's Google+ product. And at the same time, has changed G+ so that anyone can now sign up, you no longer need to be invited by another G+ members.
While the G+ searching gives results that look very much like stream items, and you can move forward and back with the k/n, k/p keyboard shortcuts, they are not streaming. The resultant page is static like your incoming and notification page. But, because the items are individual and you can hotkey forward and back, it leads me to believe that the search results may eventually change, and may scroll real time. This would be very much like the old Google Real-time product, and would allow you to search on "ancient history" and then sit on the page and watch new items that meet that search appear if new items are added to the web while you watch the page. If/when this happens, this will make G+ really fantastic.
You can also save searches, and a link to them appear below your circle items.
G+ is improving, although there are still a number of things that are keeping me from using it as my blog. While many might not use it because of all the extra buttons/links that one can follow on a G+ page that you don't have on a blogspot or wordpress blog, that is not the reason I am not currently using it. The reason I have not committed to it yet is rather technical.
Because I am constantly experimenting with web pages there are things that I notice that the average blogger may not. Here is my biggest current complaint with G+. It you make a G+ post item, and make it public, that item will appear on google searches. So my name being "Rich Griese" If you search on the regular Google search engine, you will see G+ post entries that I have made. This seems great, and it is. In fact, these G+ entries appear higher than most other entires in the search. The problem comes when you delete a G+ post entry. I have found that even after you delete a G+ post it continues to appear in Google search results. And, if you navigate to it, it actually appears. This makes managing your entries a nightmare. You make a G+ post entry, and later delete it on the G+ product. But, that items appears on a google search, and if you navigate to it from the Google search page, it actually shows the page. So, you think you deleted a G+ post, but it can be navigated to.
Now, sometimes if you do a Google search and navigate back to the G+ post item you deleted on the G+ product, and it appears, and you delete it again, Then often it will show a G+ 404 page, i.e. page not found. But in effect you have to delete the item twice, once in G+ and then again by navigating to it via a Google search. Plus, even after you have deleted it a second time, the item still shows up in a Google search, even though when you navigate to it, you get the G+ 404 page.
It seems to me that Google needs to do a better job at allowing users to delete items, and making sure they are delete through the entire Google world.
And... it seems to me that since G+ posts have the user big fat google number in them, that they should also change their G+ 404 system, so that if you navigate to a deleted post of a particular users, instead of showing a page not found page, they should redirect to that particulate users Google profile.
If Google handles this kind of stuff better, I would probably give up all my other web blogs, and just start blogging with G+ post items.
