A good quotation about the potential unreliability of Emporis:

Can you please cite your source for the recent change made to the Taipei 101 page (regarding the Sears Tower antenna height)? The Emporis database keeps track of these things as closely as anyone, and it shows an antenna height of 1728.98 feet with the CTBUH as a source. Of course Emporis is wrong sometimes, but if you have a better source please divulge it so everyone can be corrected. Thank you, Montalto 09:02, 18 June 2006 (UTC)
