Gavin Bowman, proprietor of V4 Solutions, writes what he calls the "Obligatory Blog" (he says: These days if you run a software company, you have to have a Blog. This is mine).
Gavin is a MicroISV and subject of my first interview on The MicroISV Show, who now has a second product, congratulations!
On his blog, he does a weekly chronicle of doings in the MicroISV space under the headings of: News and Announcements, Relevant Blog Posts and Articles and Further (mostly relevant) Reading.
If you're a MicroISV, or want to be one, check out Gavin's Obligatory Blog regularly.
