Looks like people are only capable of and willing to use webcrap these days. AFAIK, gmail accounts can be accessed via IMAP (although gmail's IMAP is a bit wonky), even several of them from one place.
I can't understand this obsession with giving random 3rd party services on the web access to personal stuff.
I have 10 e-mail addresses I use day-to-day and I access them all in Mozilla Thunderbird through IMAP. I haven't found a webapp anywhere near as straightforward and efficient as a simple desktop mail client. I definitely don't want to log in to 10 different web apps to check my mail, or even log in to one and sequentially click a "switch account" button and cycle through things.
You'll be able to do this with Loggur when it's ready, no problem... along with a number of awesome ways to sort, filter, graph, push/pull data, and set triggers.
