I prolly have half a dozen different LJ clients installed across various computers, and realistically, it's not much harder to switch from e-mail over to one of the LJ clients, or even the LJ webpage. But for some reason, it just seems easier and more convenient to send posts via e-mail.
I can only suppose it must be due to the huge amount of time I already spend with e-mail. I could handle losing my telephone (landline and cell phone) much easier than I could deal with losing my e-mail. E-Mail is, with the exception of face-to-face interaction, my most important means of communication.
Oh, well. That's your warning. Be prepared for more journal entries from me in the future. ;-)
