border ...the post itself....something to constrain/differentiate it from the surroundings..and other post..especially on larger monitors
contrast..may be less of an issue with the above in place but consider going with a higher contrast between the font and background (within the border mentioned above)...less taxing to read
In the process of moving so I will try and play around with it sometime next week then you maybe you can give me some more feedback. BTW-thanks! . Saw you on my site this morning...
