answer:If you want a blog, it’s easy to make one. Certainly if you wish a private blog this is easily done by installing WordPress or similar. If you are looking for a native (i.e. non-Web-based) application that does the same thing I must say I don’t know of any app in the Ubuntu repositories that does what you want. This does not mean it isn’t there. There are more than 35000 different programs in Ubuntu’s repos, and I am not familiar with all of them. You might try asking the Ubuntu forums. There are literally thousands of Ubuntu users sharing knowledge there.
