I would love to be able to export messages based on the hash tag....I.e., only messages tagged "journal". Or perhaps, in the complete export, add an additional data column for entries that is just the hash tag associated, so the entries can be sorted in excel easily.
Not really a necessity, but the ability to message pictures? That'd be awesome, although I have no idea how this would interplay w the export.
I'm curious how many users you have currently? The reason I love this project is both the ease of text messaging and the time stamp inherent in that. However, I think creating a phone app that would function, not as the point of data entry, but as an easy way to view data/analytics could be a great way to increase exposure and get more users. I set up a bookmark on my iPhone home screen so I can easily go to the web based log in to view entries by hash tag, but an app would work just as well, if not better.
Hope to hear back! I encourage you to keep this experiment going... So much potential!
