like Evernote. It does exactly what you're looking for.
I have lots of technical articles/scripts/notes which i would like to manage using software similar to blog concept.
I can create/edit post of each articles/notes in a web browser locally in my system with searching capabilities. so that anytime i can dig into my old notes by searching.
Also,i see there are lots useful notes in the websites, so i should be able to copy & paste the contents locally on my offline web page to refer them later.
Can somebody suggest me ?
