The Homeless Guy has listed the posting of his link at MetaFilter as the main reason for his site's ultimate take-off in popularity. It's an interesting account of the effect that a little link on MeFi can have on an individual blogger: This posting on Metafilter generated some 900 visits to my blog that day. The following day an online magazine in the UK mentioned my blog (apparently after someone read about it on Metafilter) and my site received 1200 visits. The following day brought 3200 visits. The next day, Yahoo listed my blog on its list of "New and Notable" web sites, and it received over 15,000 visits. Go, MeTa.
