This may apply to 'small fry' as much as it does to larger companies but the wandering eye of the SEC will make a special exception for you when you do this for a public company. That is when they go after you with a bunch of very sharp pitchforks. Companies that have only had private investment and investors that are not about to sell or buy stock in those companies at the time they make their blog posts or other communications probably have very little to fear. That said, it is probably good policy not to write about any companies that you have an active stake in, especially while transactions are in progress. The people involved in public companies all have been 'read their rights' on this stuff and know full well the consequences of breaking the rules.
