The way to achieve a meaningful life is not through finding love, cultivating friendship, building a corporation, founding a nation, or creating a masterpiece.
The only way to be sure you matter(ed) is to make it onto Wikipedia.
Of course, you can't write your own entry, so you'll have to do something wiki-friendly.
Once you get on there, you can track the progress of your life--at least, your life as Wikipedia knows it--secure in the knowledge that you've at least hurdled the bar.
Oh, and the title? Wikiheaven, wikitopia, and wikihalla were all taken.
