i would like to publicly share the details of my investment portfolio. what websites add value in this regard?

this is going to be a bit of a shameless plug, but i've build a portfolio tracking website to track your portfolio and be able to share it (in read-only mode) as  well. it is at http://frano.carelessmusings.com and currently in beta. most portfolio trackers are behind a login wall and thus will lack the sharing function you are looking for. examples of these are: yahoo finance, google finance, reuters portfolios, morningstart portfolios, and many others. another very quick and easy solution (if you are not trading too often) is a shared google docs spreadsheet. gdocs has integration with google finance and can retrieve prices for stocks by symbol. a spreadsheet can contain the following: symbol, quantity, avg. buy price, price, p/l, p/l% and so on. the current price and p/l data can be functions that use the google finance api. hope this helps, and if you check out my site please let me know what you think and what i could change.
