If you are an Android developer, you might be familiar with the excellent ACRA library which allows you to receive your Apps crash reports into your Google Docs account as a spreadsheet.
The only problem is Google Docs Spreadsheets fail catastrophically once they get to a certain size, you cant open them therefore you cant reduce their size, you cant download or export them. And if you choose to delete them then you will lose the connection between the App and the spreadsheet thus loosing any future crash reports (the spreadsheet and the app are linked by a form key imbedded in the App and unique on Google Docs).
