Before Google retired Google Notebook, I was a happy user, cause sharing to Notebook worked quite well. I have tried evernote and other tools, but it was not quite that handy for me.
My new notebook solution
Shortly after Google Plus started the sharing feature, I created a circle called bookmarking with just me as the only one in the circle. I used it a lot, but it was not very useful until G+ plus got its searching feature.
Now, when I find something on the internet or on Google+ I just share it to my bookmarking circle. I use hashtags for all the little snippets I share into my bookmarking circle so searching is more easy now.
I also use the +1 chrome extension, which allows me to share even, if there is not +1 button on the page.
So Google+ has become my new notebook for all things, I find bookmarkable. And editing, deleting and resharing is possible, so I could insert hashtags into older bookmarked shares of my own.
Search becomes really easy, if you know another little search trick. If you want to search only for your own postings you can include in the search slot the following from:<google-21numbers-id> as you can see in the following screenshot. You get your own Google Id by going to your profile and looking at the URL. There you find the 21 digits of your Google Id.
So enjoy your little Google Plus notebook and bookmarking tool.
