I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

NGC 290 is an open cluster of stars in the southern constellation of Tucana. This cluster was discovered September 5, 1826, by Scottish astronomer James Dunlop.[7] It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy.[8][2] The cluster is an estimated 30[5]–63[4] million years old and is around 65 light years across.[2][9]
