I don’t seem to be the only one who’s got problems to remember what exactly I did a couple of days ago, which is where Memiary comes in. Memiary is a neat web2 application that allows you to enter each day five things you’ve done. The entries favour kind of Twitter style brevity to create a mini-journal to jog your memory. One thing is missing though: a search function.
Go to Memiary, follow the easiest sign-up process i have ever seen, and start using your brevity journal.
