I just found this letter to Sergey and Larry!
Dear Sirs, My colleague and I use Google everyday we can. It makes us smarter and gives relevent results to almost all of our search queries. We are so grateful for its service, we have been working to make it better and we believe we have. Before the Google API, we used screen scraping techniques to allow us to save our searches and the links that we would click on. From there, the API has allowed us to increase the sophistication of the utility to do much much more. We believe our creation would be very valuable to Google in that is improves the level of service you provide to the average and power user, as well as quantify the audience to your advertisers more clearly. These means improve revenue and secure growth by reducing user attrition. We are most interested in presenting our concept to Google, but more specifically the two founders. We believe the vision and aptitude of Sergey and Larry will appreciate the conceptual highlights of our progress. Please let us know if this can be arranged. Thank you very much for your consideration. Sincerely, Albert L. Lash, IV and Ryan Overbeck
