October 13th on Security Now Steve Gibson and Leo Laporte had Joe Siegrist of LastPass to talk about the acquisition of LastPass by LogMeIn. Looks like for now Joe will remain at LastPass to run things. Joe said that LogMeIn had no plans to change things, at least for now.
I gather from this conversation that there is nothing to worry about for the near future. I will continue to use LastPass for its reliability, security and convenience.
