I probably would have followed his blog.  Here is what Wikipedia has to say.  Here is what Lucian had to say. Here is an excerpt from Lucian:

"He was no half-baked enthusiast either; he had lived with the poets, and knew most of them by heart; he was a practised speaker; he had a knowledge of philosophic principles not of the superficial skin-deep order; he had developed and hardened his body by exercise and toil, and, in short, had been at the pains to make himself every man's equal at every point. He was consistent enough, when he found that he could no longer suffice to himself, to depart voluntarily from life, leaving a great reputation behind him among the true nobility of Greece.
Instead of confining himself to a single philosophic school, he laid them all under contribution, without showing clearly which of them he preferred; but perhaps he was nearest akin to Socrates; for, though he had leanings as regards externals and plain living to Diogenes, he never studied effect or lived for the applause and admiration of the multitude; his ways were like other people's; he mounted no high horse; he was just a man and a citizen. He indulged in no Socratic irony; but his discourse was full of Attic grace; those who heard it went away neither disgusted by servility nor repelled by ill-tempered censure, but on the contrary lifted out of themselves by charity, and encouraged to more orderly, contented, hopeful lives."
